The first thing that comes to mind is Harry Potter 3, which probably isn't quite what you're looking for.

Any fan of the book (or someone who's read it recently, at least) can tell you that the film is missing a few bits of info that make the ending all make sense.

It's been awhile for me. What's the film missing? (the films and the books all blur together for me)

I can't tell you with the razor like accuracy I could have several years ago, but IIRC, it has to do with Harry's Dad's friends and their relationship to the maurader's map and that Harry's dad's patronus was a stag. Some part of that or all of it. I just remember being shocked that they left maybe a sentence of exposition out that sort of tied it all up in a neat cherry on top. Not to mix metaphors.
