David Koepp’s Mortdecai may be adding Olivia Munn according to Deadline. While her possible role is currently unspecified, it was confirmed that she would star opposite of the previously added actors: Johnny Depp, Ewan McGregor and Gwyneth Paltrow.

The upcoming project from Koepp is a big screen adaptation of “The Great Mortdecai Moustache Mystery” by Kyril Bonfiglioli. The fourth chapter in the author’s Mortdecai series (which also includes 1972’s “Don’t Point That Thing At Me,” 1976’s “Something Nasty in the Woodshed,” and 1979’s “After You with the Pistol”), the novel was published posthumously in 1996. It follows Charles Mortdecai, a debonair art dealer and part time rogue on race to uncover a lost bank account filled with Nazi gold.

Munn most recently can be seen as a series regular on HBO’s “The Newsroom.” She also appears in films The Babymakers and Magic Mike.
