The 'Hangover' Wolfpack Offers Updates On 'Vacation' Reboot And 'American Sniper'

Last week, we traveled to Las Vegas to sit down with the Wolfpack to talk "The Hangover" for one last time before the trilogy ends next week. We'll have more about that movie closer to the release date, but we took some time out of our interview to ask a few questions about Bradley Cooper's and Ed Helms' upcoming projects.

A few weeks ago, Steven Spielberg signed on to direct Cooper in an adaptation of "American Sniper," the tragic true story of Chris Kyle, whose memoir the actor's production company optioned. Cooper shared his reaction to attracting such a legendary director.

"I mean, it's insane. It's a book I read and one my production company optioned," Cooper said. "This guy, Jason Dean Hall, wrote a version of the script. [Spielberg] read it last week or two weeks ago."

The news unfortunately caught Zach Galifianakis by surprise. "Wait, wait, wait. You're doing a Steven Spielberg movie?" he asked before storming off.

Once the room had cooled down, Helms offered a quick update on his delayed "Vacation" reboot. "Yeah, we're waiting. Spielberg's going to direct that too," he said, and Galifianakis left again.

Getting back to the truth, Helms confirmed that the delay had to do with a disagreement about the appropriate rating for the movie, PG-13 versus R. "There was some dispute on what tone the movie should take, and I'm always on the side of whatever's funniest," he said. "Really, it came down to a question of, does America want to see Ed Helms naked?"

"And that answers is unequivocally, 'Oh, yeah,' " Cooper added.

Helms remains hopeful that what he calls "business considerations" will get sorted out. "There's a business behind this business. Sometimes it gets in the way of the creative process or delays the creative process. That's kind of where we're at," he said. "I hope, I really hope that it gets worked out because I love, love this 'Vacation' movie, and I can't wait to do it."

"The Hangover Part III" opens on May 23.
