Thundercats...HO!

This incredible fan-made trailer for a Thundercats movie is awesome on several levels. It looks great, and it's very well edited, which already puts it above most fan videos. The trailer is assembled entirely from footage of other movies, photoshopped with crazy skill to transform Brad Pitt from Troy, Vin Diesel from the Riddick movies, and Hugh Jackman's Wolverine into Lion-O, Panthro and Tygra. They all look pretty authentic, as do the Spy Kids as WilyKit and WilyKat, and the CG Garfield as Snarf (finally, Garfield the movie has a use).

Even more impressively the creator managed to grab sound clips of the actors saying appropriately Thundercatty things, and even assemble clips to make it sound like Diesel and Jackman are saying "Lion-O." Frankly, even if a real Thundercats movie ever, ever gets made, it will probably never look even half as good as this trailer.
