he met “waterborne” writer / director ben rekhi and co - producers smritri mundhra and salvy maleki while working on “o brother where art thou? ”” (rekhi) came to me with the money and the script, and i used some of my l. a. contacts to pull together a crew, ” phillips said. “he’s very concerned with material elements, like water and oil, which goes along with the main threat in the film. ”phillips is one of the youngest filmmakers to join the director’s guild of america. he wrote his first screenplay, “the americans, ” while on vacation in europe, and is working on his second. “waterborne” was his first film as a producer. phillips had heard of and briefly met muxworthy, and invited him among dozens of other actors to play the part of bodi. ”bodi is a lumberjack, and jake had worked in saw mills, so there were a lot of parallels, ” phillips said. “he fit the role perfectly. ”muxworthy also grew up in carbondale and graduated from yampah mountain high school. he made his feature film debut playing an out - for - trouble skateboarder in “grind, ” opposite adam brody and mike vogel .
waterborne’s writers (director coonan and richard barcaricchio), had been working on a zombie feature film set in an australian country town for some time when they agreed to make their short as a ‘proof of concept’ film. deciding their feature should include not only humans being infected by the blood - thirsty virus, but local wildlife who also drank from the contaminated water supply, the pair knew if they wanted people to support the film, they would need some kind of proof that it’s going to work first. “we wanted to explore the world that ryan and richard had created in their feature film script”, says vfx supervisor / editor / colourist chris tomkins, “and give the zombie genre a uniquely australian twist, and what’s more australian than a zombie kangaroo? for many australians, encountering a stubborn kangaroo on a country road is a common experience and we wanted to put a genuinely creepy slant on this occurrence. and for the international audience, who already view australia as a bit of a scary place, we wanted to further drive home the idea that our wildlife is terrifying! but from a practical standpoint, we also wanted to experiment with the combination of practical and visual effects to create our zombieroo, especially with the feature film in development” .
among our other exciting screenings this year are shonali bose' s amu, on the assassination of indira gandhi; chicken tikka masala, a film on a gay man' s attempts to avoid his family' s arranged marriage proposal; waterborne, a post 9 / 11 saga by smriti mundhra. complimenting them are some very compelling documentaries like mystelle brabee' s highway courtesans, academy winner born into brothels, continuous journey and runaway grooms by ali kazimi and a host of short narrative and documentary films .
the non - profit group, which works to promote equal opportunities for women in the film industry, chose the recipients from more than 250 feature - length narrative films, documentaries and shorts .
having developed a love for the blood - soaked films of george a romero, sam raimi and peter jackson as a teenager, it warms my heart to see practical fx still in use in a time when cgi is so readily available. recent shorts from ray sullivan, chris mcinroy and brian lonano have showcased there’s still a passionate audience for these “gore” films and waterborne not only taps into this market, but also the recent trend of tongue - in - the cheek thriller’s (sharknado i’m looking at you !) featuring animals running rampage (although waterborne’s blend of horror / dark - comedy feels more akin to jonathan king’s black sheep than these aformentioned films) .

shot on location in regional victoria, australia, the film only came about due to the amazing support from over 250 crowdfunding backers, who helped fund the creation of an incredible zombie kangaroo puppet, as well as a digitally animated zombieroo .
with waterborne’s main attraction its zombieroo, i couldn’t turn down the opportunity to quiz vfx supervisor tomkins about creating his murderous marsupial and how they went about bringing him / her to life. “it was definitely the most complex short we’ve ever made” says tomkins, “filming overnight in freezing conditions and isolated locations, utilising special effects, visual effects, puppetry, guns, and explosions all at once! the most unusual aspect of the whole film was creating a zombie kangaroo combining both practical and visual effects. a good deal of the film features the zombieroo puppet, which was also augmented using vfx to blink, snarl, etc) but then we also had an entirely digital zombieroo (which was used in the wider shots or whenever you see the full body or bottom half, given our puppet is only waist - up). trying to merge these elements to create a seamless creature was difficult, but we’ve had many people ask which scenes use the puppet and which are the digital roo, so hopefully we’ve achieved our goal! ”
the waterborne polyurethane polymer of the present invention is synthesized by reacting a polyisocyanate with an active hydrogen containing, high molecular weight product, such as a long - chain polyol or a long - chain poly amide, and a water - solubilizing compound having water - solubilizing groups to form an isocyanate terminal prepolymer. the prepolymer is subsequently neutralized with a tertiary amine and dispersed in water. the dispersed prepolymer is then chain - extended using a functional primary and / or secondary amine having at least 2 active hydrogens .

if you enjoyed crash you will undoubtedly enjoy this. similar story - similar structure - similar music. if your into films in any way you' ll appreciate the that the final cut of this movie was made on a very small budget, but gives the feel of a much bigger movie. there is a believably tense atmosphere throughout the movie which is further drove into your being by the excellent music (very similar to crash). the running time is short - but leaves you feeling as though you' ve seen a lot more. the film is a character based one and is driven along by some pretty good acting. but the film is really too short for any of the leads to really stretch there acting skills. the main guy is actually the oldest brother from
malcolm in the middle
and after watching this i hope he gets more work in the future. a very good film overall - my buddy thought it was super sweet. who am i to disagree! !! !! !! !! !! ! watch! !! !! !! !! !! !

the most common allergic response is type iv, a type of contact dermatitis caused by not only the protein in natural rubber latex, but by the additives which improve its properties. these additives include sulfur and sulfur based chemicals and accelerators, mercaptobenzothiazoles, thiurams, carbamates, and phenylene diamines. the type i is the most serious, and possibly fatal, allergic response. because of these past problems associated with the manufacture and use of rubber, polyurethane materials have been substituted for rubber in some applications. polyurethanes are advantageous because they can be biocompatible, can be foπned into films with high water vapor transmission, are cooler to wear, and are oil resistant and do not swell in the presence of body oils. use of these prior art polyurethane materials, though, has been problematic for several reasons. for example, many of these materials must be extruded, the. rmofo. rmed or solubilized in an organic solvent to be shaped for use. further, many of these prior art polyurethane materials are synthesized using a solvent, which can be detrimental if the resultant polyurethane material is used in applications necessitating a solvent - free polyurethane, i. e. , protective devices such as condoms, gloves, and catheters. thus, both safety and environmental considerations have necessitated a search for a waterborne, water - soluble, solvent - free polyurethane .
a prepolymer diluent may be used to render the viscosity of the copolymer dispersion low enough to process the product. the preferred prepolymer diluent is n - methyl pyrrolidinone (nmp), because it does not contain reactive groups, which will interfere with the reaction. it is preferred that a minimal amount of the n - methyl pyrrolidinone (nmp) be used, preferably in a range of 0 - 10% n - methyl pyrrolidinone (nmp) by weight of the polyurethane dispersion. the maximum amount of n - methyl pyrrolidinone (nmp) used is preferably 10. 0% by weight of the resultant waterborne polyurethane dispersion. however, the copolymer dispersion is preferably prepared in the absence of a diluent. in this case, the prepolymer should be made in a way that will minimize its resultant viscosity. in neat (no solvent) and solution polymers, viscosity is largely determined by the molecular weight of the polymer. to minimize the molecular weight of a finished prepolymer, an nco / oh ratio of 2 / 1 should be used. in this way the diol portions are essentially endcapped by the diisocyanate species, leaving an isocyanate terminal prepolymer of relatively low viscosity. as the nco / oh ratio of a prepolymer is reduced, the resultant viscosity increases dramatically. it is recognized that cosolvent free materials can be made at below 2 / 1 nco / oh ratios, but they become more difficult to process, pump, stir, etc. also, . higher temperatures will be needed to work with such a prepolymer .
“tribe” directed and produced by jordan bryon tribe is about lgbt arabs risking their lives to be themselves in muslim - majority jordan. we follow the young bedouin trans - woman fleeing her tribe before they discover her secret transition; the iraqi refugee murder - witness whose tribe are hunting him; and the australian filmmaker determined to help without understanding the price of freedom in the middle east. these are some of tribe’s threads - a powerful new film that weaves together the hidden beauty and tragedy of queer lives in jordan. snapshot bio: emerging documentary filmmaker and activist jordan bryon has worked on human rights films in australia, uganda, india, jordan, and afghanistan. head miles saw jordan enter a medium - security men’s prison alone and follow the prisoners on their journey to redemption through creative expression. jordan embeds in hidden communities and builds deep relationships with people, allowing her camera to capture their rawest moments and present the tenderness, courage, and beauty that exist in struggle .
as the nco / oh ratio of a prepolymer is increased above 2 / 1, the molecular weight will be limited as with the 2 / 1 ratio, but the excess diisocyanate will function as a diluent, further reducing viscosity. while this is a desired effect, raising the nco / oh ratio above 2 / 1 can also have negative effects. when isocyanate content of a polyurethane is increased, the hardness, or modulus of the polyurethane, along with the yield point, is increased. this is undesirable for producing a

polymer. also, when excess diisocyanate (obtained from using an nco / oh ratio much greater than 2 / 1) is introduced into a dispersion, and this dispersion is then extended with a primary (or secondary) amine, high molecular weight polyureas may be formed. these materials are not soluble, but by controlling the ratio in the range of 1. 8 to 2. 3 the results will be satisfactory. if an excess of isocyanate is used the result may be gels or grittiness in a cast film, and sediment in the dispersion. this can lead to weakened films, which have a poor appearance. for these reasons, an nco / oh ratio of about 1. 8 / 1 to 2. 3 / 1 are desirable, and ratios of about 1. 9 / 1 to 2j / 1 are most desirable .
. another important factor in keeping prepolymer viscosity low is in the selection of raw materials, and the amounts in which they are used. the prefeιτed isocyanates for this invention are isophorone diisocyanate and 2, 2, 4 and / or 2, 4, 4, trimethyl hexamethylene diisocyanate, due to their positive effects (high strength, low modulus, low prepolymer viscosity) on processing and film properties. to further reduce prepolymer viscosity, a polyether polyol may be substituted in whole or in part for a polyester polyol. the preferred polyether polyol is acclaim 3201, due to its low viscosity when reacted into a prepolymer, and due to its low monol content vs. conventional polyethers. the acid content of the water - solubilizing compound is yet another consideration for producing a low viscosity prepolymer. higher acid numbers will lead to higher viscosity, but there is also a minimum amount of acid needed to render a given polyurethane backbone dispersable. the preferred carboxyl containing diol in this invention is dimethylol propionic acid. the prefeired range of carboxyl containing diol or water - solubilizing compound is from about 2 wt. % to about 4 wt. % of the total prepolymer. the amount used will approach 2 wt. % as the backbone becomes more hydrophilic, as with higher concentrations of polyether diol. as the backbone becomes more hydrophobic, as with polyester based systems, the acid content needed for dispersion will approach 3 - 4 wt. % .
