Screenlife or computer screen film is a genre of visual storytelling where all the events are shown on a computer, tablet or smartphone screen. It became popular in the 2010s with the growing impact of the Internet. According to Timur Bekmambetov, the Russian-Kazakh director and producer, a computer screen film should take place on one specific screen, never move outside of the screen, the camerawork should resemble the behavior of the device's camera, all the action should take place in real time, without any visible transitions and all the sounds should originate from the computer. There have, however, also been movies that switch between screens and still categorized as screenlife. After producing one of the first mainstream feature-length computer screen films, Unfriended, in 2014, Bekmambetov popularized screenlife as a narrative device in film. From Wikipedia
