James Marsden, Catherine Keener and Tracy Morgan are about to get "Nailed."

Boy, that's a pun that we're never going to tire of.

In any case, those three actors are in final negotiations to join Jake Gyllenhaal and Jessica Biel in the wacky sounding David O. Russell ("Three Kings") comedy "Nailed."

Written by Russell and Kristen Gore, "Nailed" focuses on a woman (Biel) who gets a nail shot into her head and begins to experience erratic behavior (the original Hollywood Reporter story on the movie said the nail caused "wild sexual urges," which sounded more exciting). When she heads to Washington to lobby for better health care, she becomes involved with a fresh-faced Congressman (Gyllenhaal), who has to decide whether to help her or take advantage of her.

The trade paper now says that Marsden will play the small town boyfriend of the main character, with Keener as an unscrupulous legislator. The trade adds that Morgan will likely play another victim of a bizarre injury who joins the main character's cause.

Marsden, best known for "Superman Returns" and the "X-Men" movies sung his way through 2007 in "Hairspray" and "Enchanted." He started 2008 off right with the romantic comedy hit "27 Dresses."

"The 40-Year-Old Virgin" co-star Keener earned award buzz for her turn in "Into the Wild."

Morgan stars on NBC's "30 Rock" and the upcoming "Superhero Movie." He was last seen in "First Sunday."
