So this is an collection of two animated shorts to form a movie.
Hulk Vs Wolverine
Hulk vs Thor
So far I have only seen Hulk vs Wolverine, and its more a Wolverine feature than it is a Hulk one, but we do get to see Team X which is Deadpool (who is awesome in this movie), Omega Red, Sabretooth and Lady Deathstrike.
Its cool and brutal and bloody.
