Anthony Anderson isn't afraid to play a psychotic cop killer in a movie -- telling TMZ, he'd happily accept the role of Christopher Dorner in a film about the accused murderer's life ... as long as the script is good.
Anderson was leaving Mastro's Tuesday night alongside Don Cheadle and the vaporizer-carrying George Lopez when our photog asked if he'd be open to the role ... given Anderson's resemblance.
Anderson replied, "I'm always up for a good role, brother."
So ... you buyin' it? Our vote's still for LL Cool J.
