Valve recently released their Source Filmmaker (SFM) tool free to the public, which was awesome of them. SFM can be used to easily make computer animated movies using characters from Team Fortress 2 and (eventually) characters from other Valve games. We already posted fifteen of these funny fan-made animations here, and we posted SFM versions of scenes from Pulp Fiction and Back To The Future here.
The first video below is a re-creation of the “zip it” scene from Austin Powers: The Spy Who Shagged Me. After that is a Captain Falcon homage which reminds me I picked the wrong day to stop sniffing glue. We also have the Joker interrogation scene from The Dark Knight.
The last two are my favorites so far, a reminder to never play Nickelback and a re-creation of the greatest scene ever committed to film.
