The red-band trailer for the R-rated comedy Bachelorette has gone online.  The film stars Kirsten Dunst, Lizzy Caplan, and Isla Fisher as three deeply self-centered bridesmaids who go on a hunt to repair their friend's wedding dress after they ruin it.  I caught the film at Sundance, and thought it was at its best when it was being unapologetically mean-spirited.  However, the movie loses its momentum when writer-director Leslye Headland tried to explain why her characters are such horrible people.  The tame all-audiences trailer didn't do a very good job of selling the film, but the red-band does a better job of show off the humor, especially the jokes from Caplan.  It still doesn't want to show how bitter and angry the characters are, which is fine.  Why spoil some of the best jokes?Hit the jump to check out the trailer.  The film also stars Rebel Wilson, James Marsden, and Adam Scott.  Bachelorette hits VOD on August 10th, and hits theaters in limited release on September 7th.Trailer via Funny or Die.

Here's the official synopsis for Bachelorette:

On the night before an old friend’s wedding, three frisky bridesmaids go searching for a little fun but find much more than they bargained for. With lovely Becky (Rebel Wilson) set to marry her handsome sweetheart, Dale (Hayes MacArthur), the remaining members of her high school clique reunite for one last bachelorette bacchanal in the Big Apple. Regan (Kirsten Dunst) is an overachieving, ueber-Maid of Honor who’s secretly smarting over the fact that she’s not the first to marry, while Gena (Lizzy Caplan) is a whip-smart sarcastic who’s actually a closet romantic, and Katie (Isla Fisher) is a ditzy beauty who loves the good life. But when Becky insists on keeping the bachelorette party tame, the women proceed with an after-hours celebration of their own.
