‘Girls’ Star Zosia Mamet to Workshop Reese Witherspoon Role in ‘American Psycho’ Musical (Exclusive)

Benjamin Walker stars as homicidal investment banker Patrick Bateman, and she’ll play his girlfriend

“Girls” star Zosia Mamet will workshop the role of Patrick Bateman’s girlfriend in the upcoming “American Psycho” musical starring Benjamin Walker, TheWrap has learned.

Rights holder Act 4 Productions and producer Ed Pressman (the “American Psycho” movie) are behind the U.S. musical adaptation of Bret Easton Ellis’ classic novel, which could be heading to Broadway in the spring, according to media reports.

Duncan Sheik scored the Rupert Goold-directed London show starring Matt Smith of “Doctor Who” fame, while Roberto Aguirre-Sacasa wrote the book.

The show’s U.S. production finds“Bloody, Bloody Andrew Jackson” star Walker taking a stab at the role of homicidal investment banker Patrick Bateman. Mamet is playing the role of Evelyn Williams, originated by Reese Witherspoon in Mary Harron’s 2000 movie starring Christian Bale.

Sources caution that should the production head to the Great White Way, the role hasn’t been offered to Mamet, who is merely workshopping the part, nor is it clear whether Mamet’s schedule would allow her to commit to a Broadway run. However, it’s unlikely a popular TV actress like Mamet would be asked to participate in workshops if the producers had no intention of bringing her to Broadway.

Between “American Psycho” and the upcoming indie movie “Shiva and May,” Mamet continues to tackle challenging opportunities that showcase her range as an actress, and like her “Girls” co-star Allison Williams, she’s able to carry a tune. The actress has also been under consideration for “Time After Time,” a movie musical in development at Summit, which produced the hit “Twilight” series.

Mamet is no stranger to the world of theater as she’s the daughter of acclaimed playwright David Mamet. Best known for playing Shoshanna Shapiro on HBO’s “Girls,” Mamet has also appeared in “Mad Men” and “The Kids Are All Right.” She’s represented by UTA, 3 Arts Entertainment and attorney Stan Coleman.
