While the theatrical release was uncut, the German DVD release was cut by ca. 1 minute to to keep its "Not under 18" rating from the FSK. The uncut version was released with a SPIO/JK approval (resulting in various sale restrictions).
There is a popular fan edited version that removed certain lines of dialogue deemed corny, as well as removed scenes with poor CGI. It also has added the infamous "we're gonna get you" scene from the trailers (that didn't make the final cut).
