Kristen Wiig has said that despite her success in comedy she's always wanted to take on more dramatic roles.

The Saturday Night Live star and Bridesmaids co-writer and actress said that her true passion is being funny.

Kristen, 40, told Elle that it was " not necessarily a bad thing" to be ensconced in the world of comedy.

"But," she added, "I've always wanted to do dramatic stuff, to write and direct, do a lot of different things."

Kristen, who is enjoying a more dramatic role in forthcoming film The Skeleton Twins, said: "Comedy is where my heart lies, but there's also something really satisfying about being able to step away with a small crew, become a character and get to know her for a few months at a time."

In her new film, Welcome To Me, Kirsten plays a woman with a borderline personality disorder who wins the lottery, stops taking her medication and starts a TV talk show.

" I'd never read a character like that," she told the August issue of the mag. "I got to a scene where it read, 'She's fully naked,' and I remember thinking, 'If I do this movie, I have to do this scene, because it's really important to this script'."
