This is a fake trailer for a hypothetical Thundercats movie starring Brad Pitt, Hugh Jackman and Vin Diesel, made by cutting together footage from masterpieces such as The Chronicles Of Riddick, Troy, X-Men 2, Spy Kids and Farscape. It manages to not only be better than many of the source films, but also to get us more excited for a Thundercats movie than any real-life Thundercats movie possibly could.
Depressingly, it turns out there is actually a Thundercats movie in the works, and it will be entirely CGI and directed by a video game designer and it will almost certainly suck.
Big fat congratulations are due then to WormyTV, who apparently made this by painstakingly Photoshopping every frame of the trailer to turn Pitt, Jackman, Diesel and the rest into manimals. Took him a year and a half, apparently. Worth every minute of it.
