James Marsden Elected For a Term in 'The Butler'

James Marsden is moving into the Oval Office. The make-believe one with a lot of big hot stage lights in it, anyway.

The "Straw Dogs" star is officially the latest addition to the already ultra-impressive ensemble of Lee Daniels' "The Butler," according to The Playlist.

Marsden will be playing the role of John F. Kennedy, Jr., a position recently vacated by Matthew McConaughey (we love us some MM, but JM definitely looks the part a lot more). He'll be joining the cinematic JFK club that includes Greg Kinnear ("The Kennedys"), William Petersen ("The Rat Pack"), Bruce Greenwood ("Thirteen Days") and, of course, Ossie Davis ("Bubba Ho-Tep").

"The Butler" chronicles the latter half of the 20th century through the eyes of a White House staff employee. The film is based on the life of Eugene Allen, who started work at the White House in 1952 as a "pantry man" and served eight First Families before he retired in 1986. The amazing cast includes Alan Rickman (as Ronald Reagan!), John Cusack (as Richard Nixon?), Jane Fonda, Liam Neeson, Robin Williams, Forest Whitaker, David Oyelowo, Alex Pettyfer, Lenny Kravitz, Oprah Winfrey, Cuba Gooding Jr. and Terrence Howard.

James Marsden will be seen this fall in both "Robot and Frank" (once again playing the son of Frank Langella, as he did in "Superman Returns") and "Bachelorette." He's got "As Cool As I Am," "Nailed," "Loft" and "Red Machine" all in post-production and is currently filming "2 Guns" with Mark Wahlberg and Denzel Washington.

"The Butler" will commence with production once it's done casting half of Hollywood.
