Universal distributed The Incredible Hulk, while Paramount distributed Iron Man, Iron Man 2, Thor, and Captain America: The First Avenger. As of The Avengers, Disney has taken over distribution of Marvel Studios' films.
I'm thinking something will be worked out.
Disney would just need to strike a balance with Universal and Paramount for some % of a boxset. Surely reasonable heads would like to get a cut of what is sure to be additional sells that otherwise you wouldn't make on your own.
Universal will sell how many TIH individually vs getting some minor percentage of many units in a box set???
Seems like an easy enough situation if I'm sitting at Universal, even Paramount which has or will have already saturated the market with Iron Man/IM2 units.
