'The Dead Circus': James Marsden To Play Charles Manson

From Easter Bunny to cult leader and murderer -- it's quite a 180 turn for James Marsden.

The star, who took the lead in this weekend's family-friendly box office champion "Hop," has been cast as Charles Manson in the upcoming film "The Dead Circus." The film will take on the case of singer Bobby Fuller, whose death, though ruled a suicide, raised suspicion of foul play and potentially murder.

The story will focus on the allegations that Manson and his Manson Family were behind the murder.

Michael C. Hall will play one of Fuller's managers, while Melissa Leo takes on the role of a former Manson Family member. Hall, of course, is more than familiar with the serial killer genre as the star of Showtime's "Dexter." Leo won an Oscar for her role in "The Fighter" this year.

Marsden recently finished shooting "Nailed," a comedy co-starring Jake Gyllenhaal and directed by David O. Russell. He'll also film the thriller "Loft" later this year.
