Apple has inked deals with nearly every major studio to sell 4K movies, with Disney proving to be the lone holdout, The Wall Street Journal reports. The 4K or ultra-high definition movies will come at the same $20 price tag as high definition movies, according to a person familiar with the discussions. While Apple reportedly struggled with most of the Hollywood studios to come to terms on pricing, it was ultimately able to ink deals with the others, so it remains unclear why Disney hasn’t gotten on board yet; the studio currently sells its 4K movies for $25 on other platforms, and Apple is said to be firm on not raising movie proices above $20. Apple has long-standing ties to Disney, with the studio being the first to sell its TV shows and movies on iTunes and Disney CEO Robert Iger sitting on Apple’s board of directors. Reports from last month had Disney balking at Apple’s plan to offer new release movies for streaming just one week after they debut in theaters as other studios showed interest in the idea.
