Portal: No Escape
Creator: Dan Trachtenberg
High quality short films based on various video games are nothing new to the internet, but Portal: No Escape is particularly special because of its powerful cinematography and clever blend of action and special-effects in the latter half. Despite being a dialog-free film, it's so easy to understand the mental torment of our heroine and the rush of liberation that comes when she frees herself from Aperture Science' cold grip.
We're not the only ones with an appreciation for the flick either as director Dan Trachtenberg has recently been tapped to direct the film adaptation of Brian K. Vaughan's Y: The Last Man. Given the tone of Portal: No Escape, it's pretty easy to imagine him handling the grim source material of the comic adaptation well.
