While iCloud now lets you re-download movies you've already purchased, only four of the six major studios were initially on board when the feature first rolled out in March. But that number has now grown by one, as Universal movies are now available to download through iCloud, though those from 20th Century Fox still don't support the service. Both studios were reportedly unable to support Apple's cloud service due to contractual issues with HBO. However, when the feature first launched it was reported that both would be a part of iCloud "soon" — so it seems like only a matter of time before Fox is on board as well.
