'Bridesmaids' Trailer: Kristen Wiig, Maya Rudolph In Raunchy Wedding Comedy (VIDEO)

When you choose Kristen Wiig as your maid of honor, you know things are going to get crazy.

Wiig, who has brought to life some of the past decade's funniest characters on "Saturday Night Live," takes the leading role in a creation of her own, writing and starring in the upcoming film "Bridesmaids."

She plays the goofy yet miserably single mid-30's best friend of former "SNL' cast Maya Rudolph, who giddily asks her to be the maid of honor at her wedding. Jealous yet determined to do her best, Wiig tries to bring a misfit crew of bridesmaids together for a bachelorette party and the other traditional pre-wedding planning and rituals.

Unfortunately, it tends to end in vomit and/or disaster.

Ellie Kemper of "The Office" and Rose Byrne co-star as two of the bridesmaids, and Jon Hamm joins as well. The film is directed by Paul Feig, best known as the creator of the cult classic "Freaks and Geeks," and is being produced by Judd Apatow, famous for his guy-centric gross out comedies.
