This movie, being sold as a comedy, is actually profound political commentary on modern day Germany (and the EU in general).
Available in the US under the title Look Who's Back with English subtitles. Awesome movie.
Don't miss what comes after the credits at the end. Strange that they should hide it after the credits. Just as strange as the grainy B movie lead off before the movie actually starts. Like they were hiding what the movie was really about from political censors.
