It seems like every actor had their struggles during the tiresome premiere tour.

The end of May and beginning of June meant a new and exciting part of the trilogy for Hangover fans. In part 3, Bradley Cooper, Zach Galifianakis and Ed Helms are tracking down an escaped Mr. Chow when one of their own is kidnapped by a gangster. The poster offers some hints, with the three gentlemen looking fierce in black suits and eyewear that fits their personality. Does that sound interesting? Wait until you see the movie…

The cast of the final film in the series traveled around the world for the premieres, from the US to Europe and South America. And while it might have been fun at first, things started becoming more and more boring for Bradley Cooper. The actor was happy to take pictures with his fans at first, showing of his sharp suits and signature designer sunglasses, but when he reached Rio de Janeiro he was in a bad mood. The 38 year old not only ignored the requests of his fans, but he also gave snappy replies to reporters' questions. That is, if he even answered them at all. Rumor has it that the “Wolf Pack” actors are not real life friends, and that an earlier disagreement between the three turned Cooper in the “diva” he was at the premiere.

But it seems like every actor had their struggles during the tiresome premiere tour. Heather Graham, for example, hit the Paris red carpet in a gorgeous black and white Talbot Runhof gown. Turns out, it was too much for her to handle. The 43 year old actress went out of her comfort zone for the event, and she ended up feeling nervous through the whole thing. Graham's usual outfits are more wearable and less glamorous, but she made an exception since it was Paris, the home of couture, that she was visiting. Nervous or not, she did look gorgeous on the red carpet!
