Fans of Valve video games sure love making hyper-detailed fan movies. The latest one, Outside Aperture, tells the hidden history of what happened after the first Portal. It's not canonical, but it's cute.
Here's the description of Outside Aperture from the filmmaker Eisen Feuer:
With the fate of the main character of the game, Chell, left up in the air at the end of the game, we took the liberty of creating a fan film under the assumption that Chell lived to escape the Aperture Science Laboratories, and must now face life out in the real world. She finds an abandoned house, still stocked with food, and begins a new life with her trusty Portal Gun at her side.
Hat tip to Dan!
