OTRC: Isla Fisher talks 'Bachelorette': 'These are horrible girls doing horrible things'

Isla Fisher talks to OTRC.com at the 'Bachelorette' premiere in Los Angeles on August 23, 2012.

Isla Fisher stars as a party girl in the raunchy female comedy "Bachelorette" and the actress known for "Wedding Crashers" explained to OTRC.com how she committed to the comedy of the role.

The film is about a group of three mean girl-type girlfriends (played by Kirsten Dunst, Lizzy Caplan and Fisher) who are serving as bridesmaids for the wedding of a girl they made fun of in high school (played by Rebel Wilson). As the girls gear up for a big night out, a mishap with the wedding dress sends the night spiraling out of control.

"You know you're pretty uninhibited. You just have to go for it. You can't judge the character," Fisher told OTRC.com correspondent George Pennacchio at the premiere in Los Angeles about doing the film's raunchy scenes. "These are horrible girls doing horrible things and you can't ask yourself why you just got to commit to it and enjoy it and just try to make it as funny as you can."

Fisher, 36, is known for her role in another raunchy wedding comedy "Wedding Crashers," and "Bachelorette" comes just a year after "Bridesmaids" was a box office hit.

"Bachelorette" has already found some success before its opening in theaters. The film was released on the Video on Demand platform and on iTunes, becoming the first movie to hit no. 1 on that chart before its theatrical release.

The film also is a bit of a reunion for "Party Down" actors Lizzy Caplan and Adam Scott, who play former high school sweethearts in the film.

Caplan said of the film at the premiere, "It's pretty nasty this movie and I love every second of it."

Meanwhile, Scott said there is more to the film than just dirty jokes explaining that the film is "very, very funny. It's pretty dirty. A little mean and then super sweet and quite moving."

When asked which gender was the raunchiest in the film, Scott replied, "The women. Absolutely."

"Bachelorette" hit theaters on September 7. Check out the trailer below.
