Weird div leak???

I have weird problem. Im a newbie so please be nice:)

I get some kind of weird background leak in a theme I’m working on. I use custom posts to display movie reviews. In two posts out of ten this happens. Something appears to be wrong with the moviebox at the end of the post. Here are two examples.
