Kirsten Dunst and Isla Fisher star in a new red-band trailer for Bachelorette, Digital Spy said.

The raucous comedy drama centres on Dunst, Fisher and Lizzy Caplan as three perennially single women who are surprised when a girl they used to bully at school (Rebel Wilson) asks them to be bridesmaids at her wedding.

Released by Funny or Die, the red-band trailer offers a more explicit look at the mayhem Dunst, Fisher and Caplan's characters wreak.

The three variously insecure, ditzy and bitter women are cynical about marriage, but still decide to throw their 'frenemy' a bachelorette party, and come close to ruining her wedding in the process.

Adam Scott, James Marsden and Hayes McArthur are among the film's supporting cast.

The first trailer was released last month.

Bachelorette is written and directed by Leslye Headland, who served as a staff writer on short-lived FX series Terriers.

The film will be released on September 7 in the U.S., with a UK release date yet to be set.
