Didn't know about this and just stumbled upon it by chance. Watched it last night. Probably the best Marvel cartoon I've seen so far.
Hulk Vs is an animated film from Marvel Comics and Lionsgate, featuring the Incredible Hulk in two short film battles, one against Wolverine, the other against Thor.
You can watch it in full here.
