Beware of the Bridesmaids! Kirsten Dunst, Isla Fisher, Casey Wilson and Lizzie Caplan to Star in Film Adaptation of Bachelorette

Kirsten Dunst, Isla Fisher, Casey Wilson and Lizzie Caplan are set to star in a feature film adaptation of Leslye Headland's off-Broadway hit Bachelorette, according to The Hollywood Reporter. Headland has penned the screenplay and will direct. Production is currently underway in New York.

Bachelorette follows a group of twentysomething women who come together in a lavish hotel on the eve of their friend's wedding. The girls however have always disliked the bride-to-be, who they've known since high school, and spend their drug and booze-fueled night ridiculing her, while partying with a pair of guys they meet outside the hotel.

Dunst (Spider-Man) will play the bride, Regan, with Caplan (TV's Party Down, Mean Girls) and Fisher (Wedding Crashers) as strung-out roommates Gena and Katie. Wilson (TV's Happy Endings, Saturday Night Live) will take on the role of the maid of honor, Becky. The cast also features James Marsden (Hairspray) as Trevor, Adam Scott (TV's Parks and Recreation) as Clyde and Kyle Bornheimer (TV's Perfect Couples) as Joe. (The play featured only two male roles, Jeff and Joe.)

Directed by Trip Cullman, Bachelorette opened at Second Stage's McGinn-Cazale Theatre on July 21, 2010 as part of the company's Second Stage Uptown summer series. The cast included Celia Keenan-Bolger (Katie), Carmen M. Herlihy (Becky), Katherine Waterston (Gena), Eddie Kaye Thomas (Jeff), Fran Kranz (Joe) and Tracee Chimo (who received a Lucille Lortel nomination for her performance as Regan.)
