'Bachelorette' trailer: Kirsten Dunst, Lizzy Caplan are bad bridesmaids

A trailer for Bachelorette has debuted.

The film stars Kirsten Dunst, Lizzy Caplan and Isla Fisher as three perennial singles who are asked to be bridesmaids at their old friend Rebel Wilson's wedding.



The three marriage sceptics are surprised to be asked to participate by the girl they bullied at school, but take the opportunity to plan a blowout bachelorette party.

Nothing goes entirely to plan and the trio come very close to ruining the wedding altogether with the careless destruction of the bride's wedding dress.

Adam Scott, James Marsden and Kyle Bornheimer also star in the Leslye Headland-written and directed movie.

Bachelorette will debut in the US on September 7. A UK release date is yet to be announced.
