One upon a time, movies were released in different countries at different times. This could be done because there was no easy way to copy and store away a movie. If you lived in Italy, you could wait up to two years before you saw a popular movie. Then two things happened: it became easy to copy and store movies; and everybody in the world suddenly became interconnected. The regional segregation has ended: the only ones to believe that it's still there are the dinosaurs from a past era.

Keep in mind that a blockbuster recoups it's production cost in the first week. Most others do so sometime during their first run, typically before moving to the cheap second run theaters. That still leaves the DVD mastering costs, but that's not much compared to the cost to produce the movie. Basically, that is covered in the "just above".
Here's a sanity check: DVDs for a five or 10 year old movie in region 1 still cost well more than just a bit over the marginal cost.
