Netflix has just inked a huge deal that will make it the exclusive source for some of the biggest movies around – Disney films.

Netflix and the Walt Disney Company have announced a multi-year partnership that will bring new films to the service instantly, inside the pay TV window. Netflix will be the only subscription service for first-run Disney films, including both live-action and animated features.

The studios covered in the deal are Disney, Walt Disney Animation Studios, Pixar, Marvel and Disneynature. The deal goes into effect in 2016, where Netflix will then receive all of the theatrically-released films to stream out on a wide range of devices.

“Disney and Netflix have shared a long and mutually beneficial relationship and this deal will bring to our subscribers, in the first pay TV window, some of the highest-quality, most imaginative family films being made today,” said Ted Sarandos, Chief Content Officer at Netflix. “It’s a bold leap forward for Internet television and we are incredibly pleased and proud this iconic family brand is teaming with Netflix to make it happen.”

Netflix and Disney made a couple of other deals today, such as extended a catalog deal that allows Netflix to stream some old favorites like Dumbo and Alice in Wonderland. Netflix will also receive Disney’s straight-to-video films starting in 2013.

This is a pretty big deal for Netflix, who will be able to boast incredibly popular titles as soon as they become available for the small screen. It’s definitely a shot across the bow for a company like HBO, ans Netflix is slowly moving into their pay window. But then again, we do have to wait until 2016. Bummer.
