If you’re in America, there’s a big deadline this week — income tax filing on April 15. But there’s another deadline across the border that filmmakers all over should consider as well. You have until April 18 to submit a film to the Mobile Stories “Obsession” contest. Here’s information from the press release:

Obsession can lead to a lot of things….even winning $1,000. The National Film Board of Canada (NFB) and iThentic are pleased to announce the launch of Mobile Stories: Obsessions – six three-minute films in which award-winning filmmakers give their “take” on obsession. Made for online, mobile, and cinema, the shorts are complemented by an interactive program of filmmaking tutorials and an opportunity for viewer-generated films to participate in the Canadian Film Centre’s Shortsnonstop Festival, presented by TELUS. Mobile Stories: Obsessions is a co-production of the National Film Board and iThentic with the participation of the TELUS Innovation Fund administered by the Canadian Film Centre, the Bell Broadcast and New Media Fund, and with Canadian broadcast partner – IFC. The commissioned short films will be aired on the IFC later this year. Films and festival information at www.mobilestories.ca

Mobile Stories: Obsessions is a conversation in film. Six award-winning filmmakers — Malcolm Clarke, Shui-bo Wang, Hubert Davis, Renuka Jeyapalan, Apeman888, and Smiley Guy Productions — have created a film based on an obsession. From going bald; to fantasizing about a stranger, a loved one, or the past; to extreme customer service or the power of technology, these obsessions last far beyond their 3-minute running time. Viewers are invited to screen the films online and create their own films in response, for a chance to win $1,000 as part of the Shortsnonstop Mobile Movie Festival and a special screening at the CFC Worldwide Short Film Festival.

Even if you’re not planning to submit a film, you should check out the website. There’s a lot of info there, including a great series of tutorials on coming up with a film that narratively works for the mobile platform. (There’s also a fun “Are you Obsessed?” quiz.)
