Last Call is the first interactive horror movie in the world where the audience is able to communicate with the protagonist. To participate in the adventure, audience members submit their mobile phone numbers to a speed dial code when they buy their ticket. A special 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.
