First teased earlier in the year, Synthetic Picturehaus' amazing Portal film Lab Ratt is now complete and ready for viewing. So you should watch it.

It tells the story of Doug Rattman. Doug, aka the guy who did all the paintings you find tucked behind the walls in the game. It starts a little slow, but once things start to go poorly, the flick really hits its stride.

Lab Ratt runs for 14 minutes, so have a cup of tea handy before hitting play.
