Christina Hendricks

With new roles, Christina Hendricks and Olivia Munn head to Wall Street

EXCLUSIVE: Sarah Jessica Parker’s movie version of "I Don’t Know How She Does It," which book readers will know as Allison Pearson’s British literary phenomenon, is rounding out an intriguing cast with a trio of actors television made popular.

Hendr Christina Hendricks, Olivia Munn and SNL’s Seth Meyers are poised to join the film, according to a person close to the production.

The movie is based on Pearson’s first-person comic tale of a high-powered finance type (Parker) who’s also the mother of two young children and trying to balance the many competing elements in her life.

Hendricks, who is in final negotiations for the part and will play a friend of Parker’s character, is best known for her role as office-manager Joan Holloway on "Mad Men." (The actress perhaps most often referred to as voluptuous also had a supporting part in the recent romantic comedy "Life as We Know It.")

Munn, who’ll play a colleague of Parker’s character, is the colorful media personality from G4’s "Attack of the Show" and Comedy Central’s "The Daily Show;" she’s been making a move into film acting too, with a role in the recent "Iron Man 2". She’s also a huge Twitter sensation.

Meyers is, well, you know who Seth Meyers is.

The casting of Hendricks and Munn, both popular with men, broadens the film’s target audience beyond the traditional romantic-comedy base.

Earlier reports that Pierce Brosnan and Kelsey Grammer are joining the film also have now been confirmed; both have closed their deals, according to the person close to the production.

A Weinstein Co. rep could not immediately be reached for comment. [Update, Friday 6:47 p.m.: The company has confirmed the castings.]

The Weinstein Co. film, which is being directed by Doug McGrath (the Truman Capote movie "Infamous") is set to start shooting in January.
