OTRC: Bradley Cooper says monkey co-star in 'The Hangover Part II' deserves an award

Bradley Cooper has worked with plenty of A-list actors but the most beloved character in "The Hangover Part II" might be Crystal the monkey and the actor revealed in a recent interview that it's not his first role with the charismatic primate.

"I worked with Crystal on 'Failure to Launch' four years ago, which is crazy," Cooper said in an interview provided by Warner Bros. Pictures. "She's great! Monkey Tom is her trainer and they have their hands full in this movie, but Crystal's great. You fall in love with her the minute you see her. We have a lot of scenes together. She and Phil, well, she plays a man, which I hope she gets nominated for because she does a great performance."

In the movie, which is set for release during Memorial Day weekend, the four stars (Bradley Cooper, Zach Galifianakis, Ed Helms and Justin Bartha) travel to Thailand for Stu's wedding. Helms plays the character who famously lost a tooth in the first film and ends up with the now infamous Maori-inspired face tattoo the eve of his wedding in the sequel.

"We never got a bachelor party for Stew, he was against it for good reason, based on how the last one went," Cooper explains. "But Phil talks him into having at least one drink by a bonfire by the beach where the resort is and of course, something goes awry and that is the last memory they have until they wake up the next morning in Bangkok. And when they wake up, I don't think they're quite in the resort that they thought they were."

In the first R-rated comedy movie, which hit theaters in 2009, hijinks ensued when the four arrived in Las Vegas for a bachelor party ahead of the wedding of Doug, played by Bartha.

"Certainly Todd's idea to set it in Bangkok versus Las Vegas upped the ante completely," Cooper said. "Now being here for two months, you can see the way I look - this is lived-in Bangkok, which is the same way I felt in Vegas. You can't sort of fake Vegas for Vegas and certainly not this place."

Cooper also had nice things to say about "The Hangover" writer, director and producer, Todd Phillips.

"Todd is always the fourth character in the scene... we're all making the movie, you don't get the feeling that it was an individual. Even each role is defined by everybody... We're all so used to working with each other after the first one that it was much easier than the first movie, it really feels like we're all making it together. There was never any ego in the first one, but I certainly feel more comfortable."

Cooper's film debut was in the cult classic comedy, "Wet Hot American Summer." He has since appeared in films like "He's Just Not That Into You," "The A-Team" and most recently, "Limitless."

The 36-year-old actor was recently romantically linked to "House M.D." actress Olivia Wilde. The two have yet to comment on the report.

While it was rumored that a lawsuit over the tattoo artist's copyright on the Tyson tattoo would possible hold back the film's release, it was announced this week that the film would still open in theaters on May 26.

When asked at the recent Los Angeles premiere what he thought of having Helm sport his tattoo for the movie, Tyson told OnTheRedCarpet.com host Rachel Smith he was "honored." Tyson appears in both the original "Hangover" film and its sequel, playing himself.
