Do movie bundles get prorated for the movies already owned?

I'd like to know whether the iTunes movie bundles get prorated similarly like App bundles: e.g. I already own the The Shawshank Redemption , would I get priced the full price of The Shawshank Redemption / The Green Mile 2-Film (this is just a simple example, I'm asking because I have 3/9 movies from King of Horror: Expanded Edition 9 Film Collection and I'd like to complete that collection)
