The US iTunes Store has begun selling films from Metro-Goldwyn-Mayer Studios (MGM).

The first tranche of MGM movies reached Apple's US media download service last night. Initially-available films include titles such as Dances With Wolves,” “Mad Max,” “The Great Train Robbery” and “Rocky,” with other titles to be added in the coming weeks, Apple and MGM explained.

It's no small deal – MGM owns the largest film library in the world and has received 208 Academy Awards.

“It’s exciting to be bringing so many amazing films from our catalogue to iTunes,” said Douglas Lee, MGM’s executive vice president of worldwide digital media. “We are looking forward to adding even more films in the future so users can take their favorite movies with them wherever they go.”

“Over two million movies have now been downloaded from the iTunes Store making it the world’s most popular online movie store,” said Eddy Cue, Apple’s vice president of iTunes.

Movies downloaded from the iTunes Store are downloaded at a resolution of 640x480 (up to 480, depending on the aspect ratio) and can be viewed on a computer, iPod or widescreen TV with Apple TV.
