Retired Rapper 50 Cent's versatile acting career continues, as Curtis prepares to appear in two upcoming murder-related feature films.

The first, Robert Deniro and Al Pacino's new vehicle 'Righteous Kill,' is directed by Jon Avnet (vaguely known for directing 'Fried Green Tomatoes' and producing gangster classics 'Poodle Springs' and 'The Mighty Ducks' trilogy). Though the title sounds like a Jean-Claude Van Damme masterpiece (i.e. 'Hard Target'), Fif's role appears to be about as long as Van Damme's part in 'Breakin',' if the trailer is any indication.

'Righteous Kill' hits theaters in September 2008, so practice your "G-G-G-G-Unit" ad libs for the quiet moments, if the group has any other remaining members by then.

Next, 50 is set to star as a death row inmate in 'Spectacular Regret,' which also features Danny Huston, John Ortiz and Kelli Garner and is helmed by Joshua Leonard, who starred in the 'Blair Witch Project,' in his feature directorial debut.

Other titles for the film may have included 'Astounding Disappointment,' 'Tremendous Mishap,' and 'Astonishing Failure,' but 'Spectacular Regret' apparently summed it up best.

Check out the trailer after the jump.
