Clash of the Titans

Emma Thompson almost made an accidental uncredited cameo in this movie while visiting friend Liam Neeson on the set. Thompson, who'd been filming Nanny McPhee and the Big Bang (2010) in an adjacent studio, went to visit Neeson during a break, just as Neeson was about to shoot a scene with Ralph Fiennes and Danny Huston. Unable to exit the set fast enough as the cameras began to roll, Thompson, in her clumsy Nanny McPhee costume, had to hide behind Huston's throne during the take so she would not be picked up by the cameras.

In the filming locations in the end credits, Dinorwic quarry is credited as being in "Wales, [in] England". Wales and England are different Countries in the United Kingdom.

There are no opening credits.

Also released in a 3D version.

Edited into Yoostar 2: In the Movies (2011)
