After Tony Stark, er, Robert Downey Jr. received his MTV Generation Award last night, he blessed us all with the gift of a new trailer from the highly anticipated "Avengers: Age of Ultron" movie. In this clip we see that the Scarlet Witch has messed with the Hulk's mind, forcing Tony Stark to unveil the Hulk Buster, which leads to a great fight. 

With this in mind, it's kind of ironic that the movie hits theaters the day before the long awaited Mayweather vs. Pacquiao fight on May 2nd. Guess Tony and Bruce got on to the undercard.
