Marlon Wayans has signed on to star in Paramount actioner “G.I. Joe.”

Joseph Gordon-Levitt is in negotiations to join the tentpole, which is based on the American soldier action figure created by Hasbro.

Wayans will play Ripcord, leader of the military unit.

Gordon-Levitt will play Duke Hauser’s best friend. He is the science officer assigned to the Special Forces unit. The role of Hauser is still uncast.

War-themed story is set 10 years in the future. Stuart Beattie penned the screenplay, while Paul Lovett & David Elliot and Skip Woods contributed earlier drafts.

The Stephen Sommers-helmed film is set to start shooting next month in Los Angeles. Rachel Nichols, Sienna Miller, Adewale Akinnuoye-Agbaje and Said Taghmaoui have already joined the cast.

Lorenzo di Bonaventura, who produced the Hasbro-based hit “Transformers,” is producing “G.I. Joe” alongside the toy giant’s Brian Goldner. Sommers and partner Bob Ducsay also will serve in a producing capacity.

Paramount will release the film on Aug. 7, 2009.

Wayans, who most recently starred in “Little Man” and “The Ladykillers,” is developing a cop action spoof for Par alongside brothers Shawn and Keenen Ivory Wayans.

He is repped by WMA.
