"Windows 7 is proudly sponsoring the 54th BFI London Film Festival in partnership with American Express and working with the BFI to celebrate the UK's incredible creative talent. How? By getting you to create a 7 Second Movie inspired by your favourite film or genre. The best thing is, you don't have to be Steven Spielberg, just get some mates together, use whatever 'props' you can get your hands on and have fun! Makers of the best films will see their movie premiered at the London Film Festival."
Competition closes on the 9th October 2010 - now go make your movie!
