Billboard reports that Ludacris' CD Theater Of The Mind will arrive in stores October 21st -- the first single, "What Them Girls Like," features CHRIS BROWN and SEAN GARRETT. The CD also includes cameos from T-PAIN, THE GAME and T.I.

As for the movies, Ludacris will star in GUY RITCHIE's new flick, RocknRolla, opening October 31st, and Max Payne, based on the popular video game, on October 17th. RocknRolla, which co-stars GERARD BUTLER and JEREMY PIVEN, is about a London real estate scam. Max Payne co-stars MARK WAHLBERG in the title role; Ludacris plays a deputy police chief. He tells Billboard, "This is the first time I've played any kind of police role...my character is the dominant one over Mark. That was a power thing and I absolutely loved it."

Ludacris forsees a day when acting takes up more of his time than music. He says, "I would say that the transition is being made to where I'm getting into acting more....I think I'll always do music, but the acting, I'm definitely getting more and more into [it] and trying to see how far I can go."
