The Hangover looks like it's going to be THE sleeper hit of the summer blockbuster season. At the start of the year, few probably expected that a comedy about a bunch of guys who head to Vegas for a bachelor party would be number one at the US box office in the same month that movies like Up and Terminator: Salvation have been released.

But one of the main reasons for its success is the relatively unknown cast who make up the bachelor party - Bradley Cooper (who starred in tv show Alias and has had supporting roles in the likes of Wedding Crashers, Failure to Launch and He's Just Not That Into You), Justin Bartha (also starred with Cooper in Failure to Launch and in National Treasure), Ed Helms (The Office: US version and The Daily Show) and Zach Galifianakis (a stand-up comedian who once played the Cats Laugh Festival, also starred in Into the Wild after Sean Penn watched his little-known movie Out Cold 15 times and just gave him the part with no audition).

All four guys were in Dublin on Monday for the Irish premiere of their movie. While doing their press junket at the Merrion Hotel that afternoon, they discovered they were number one at the US box office after a tough fight with animated hit Up and there was much jumping about and whooping. Not surprisingly, they were in fine form for the rest of their interviews and a bit hyper during their chat with me, thanks to the jellybeans I brought them as a little gift.

So click below to take a listen to what they had to say about working with tigers and possibly making The Hangover sequel in Ireland...

WARNING! The following interview contains some bad language and explicit material.

All the main cast plus the director of the smash hit US comedy The Hangover were in town on Monday for the Irish premiere of the movie.

The film is another bachelor party does Vegas story - but with a twist! We don't actually see the bachelor party. Instead, the story concentrates on the morning after and neither the guys nor the audience has any idea what went down the night before - and the groom is missing!  

So the guys use all their detective skills to piece together what happened - starting with the tiger in the bathroom of their hotel suite and the baby in the closet.

Heather Graham plays Jade, a stripper who, it turns out, married one of the guys during their night of debauchery and she was thrilled to be back in Ireland to promote the movie. She appeared very relaxed and was chatty and just as pretty and sparkly in person as she appears on screen.

Also in town promoting the film was its director Todd Phillips. You're probably familar with the name as he directed some of the biggest comedy hits of the past decade - Road Trip, Old School and the reboot of Starsky & Hutch.

Todd was very friendly and kind enough to hold off the afternoon tea and fancy biscuits brought to him by room service in the Merrion Hotel until after our interview.

Check what he had to say about why comedy shouldn't be PC, how he hates the term "bromance", and how the guys (with the exception of Bradley Cooper) are just all babies by clicking on the player below.

The audience at last weekend's MTV Movie Awards were granted a sneak peek at the very first trailer for the second instalment in the Twilight saga - New Moon. Fans of the first movie and the series of books were eagerly awaiting this opportunity to see what's in store come November when the sequel hits the big screen - and they weren't disappointed, particulary with the final scene where we see Jacob turn into his wolf self.

So if you missed the MTV Movie Awards and you've not had the chance to check out the New Moon teaser, well just click on the clip below... and let us know what you think if you have an opinion on it.
