Here's a link to "This Is..." a humorous entry in the 48 hour competition that I particularly enjoyed.
This original film was made by team Death Star Holiday Chalets, who include writer Molly Brown. On meeting the team after the screening event I was particularly impressed to learn that they held a dummy run the week before - that's dedication to the cause.
Incidentally, Tube travellers over the next few weeks should watch out - Sci-Fi London festival director Louis Savy will be at large with a hi-tech portable projector screening short films and competition entries indiscriminately. You have been warned.
