Watch: Kirsten Dunst, Lizzy Caplan and Isla Fisher Get Rowdy in Red Band 'Bachelorette' Trailer

Those that saw "Bachelorette" at Sundance will be quick to tell you, playwright Leslye Headland's feature film debut is a hard-R comedy. The first trailer released by The Weinstein Company/Radius last month did a decent job of selling the film to a general audience, but a new, just-released Red Band preview, courtesy of Funny or Die, gives a better indication of the film you're in store for when it hits VOD on August 10, and opens in theaters on September 7.

The raucous, fast-paced and hilariously foul-mouthed dramedy follows a gang of old girlfriends who come together and screw everything up at their friend Becky's wedding.

The cast is led by a terrifying Kirsten Dunst as Regan, the sadistic and insecure maid of honor from hell, Lizzy Caplan as Gena, a cokehead party girl who has to confront the ex-boyfriend who she says ruined her life, and a scene-stealing Isla Fisher as Katie, a ditzy and troubled perpetual retail slave. The ladies are ably supported by a male cast that includes Adam Scott, James Marsden and Hayes McArthur.
