This should make things more interesting ahead of the early 2012 launch of Netflix’s UK video streaming service. Sony Pictures has agreed to supply Amazon’s LOVEFiLM service with exclusive access to movies including The Social Network and Salt, and animated children’s shows such as Transformers and The Karate Kid. They offer few details but call this a “major multi-year” deal and a “milestone agreement.” Amazon’s service also is licensing content from Warner Bros, Entertainment One, StudioCanal, Disney, Momentum and Lionsgate. Here’s the release:
