The first Intl. Movie Trailer Festival wasn’t afraid to ask tough questions of submissions, such as, “Would people go see a movie about Nazis in space?”Nazis in orbit was the premise of one 2010 trailer entry, “Iron Sky.” Co-founded by Ronald Sallon and Murray and Roberta Suid, the online festival and contest for movie trailers comes complete with cash prizes. The founders put together a panel of judges, a website and even fronted the $10,000 prize money. Entries covered subjects across the board: Grand Prize winner “Where My Heart Beats” was for an Afghani documentary, while Special Jury Award winner “Red Light Revolution” is for a fiction feature about an unemployed man who opens a sex-toy shop in Beijing. Sallon has partnered with Openfilm.com, a site run by James Caan, Robert Duvall, Mark Rydell and Scott Caan that focuses on getting independent films seen and is also negotiating an alliance with a distributor that will review fest entries in search of projects with potential. Sallon won’t yet disclose the company’s name. Like a good trailer, he knows how to tease.
