Last Call is the first interactive horror movie in the world where the audience is able to communicate with the protagonist. A film controlled by a member of the audience, thus blurring the boundaries between game and film. Language recognition software transforms the participant's answers via mobile phone into specific instructions. A specially developed software then processes these commands and launches an appropriate follow-up scene. The dialogue between the movie's main actress and an audience member leads to a different film - and outcome - every time: sometimes with a happy end, sometimes with a more gruesome one. To participate in the adventure, audience members submit their mobile phone numbers to a speed dial code when they buy their ticket. The moment the female protagonist takes out her phone to call someone who might be able to help her, the film's controlling software contacts one of the submitted mobile phone numbers. Once the viewer picks up, he hears the actress's voice - who tells him she would be lost without him. He has to help her escape by choosing a path through the old, rundown sanatorium. Furthermore, he also decides whether she should help other victims to flee the scene -and every single choice shapes her fate: it's a matter of life and death. 13th Street Last Call is made by Jung von Matt/Spree (Idea), Film Deluxe (Film), nhb (Sound), Telenet (IVR), AixVox and Powerflasher (Software).
