There are a handful of movies I would like to see on bluray that are currently on Vudu:

The Iron Giant - This is probably my favorite animated film of all time.

Airplane II - Not as good as the original but still really funny.

UHF - I have the HDTV rip of this one but it could use something a bit better and there are a lot of extras out there for the movie.

Also, I have the UK bluray for the original Transformers: The Movie (the animated film from 1986) along with tons of extras, including a few things that weren't on the DVD or Bluray releases but I'd love to see sort of an ultimate bluray.
