Novak Djokovic has been the top dog in the men's tennis world of late, and he's hoping his celebrity might carry over to the movie business. The No. 1 ranked player in the world by the ATP is making plans for an acting career, reports the Chicago Sun-Times.

Djokovic, winner of four Grand Slam singles titles, is known for his comedic impressions of fellow tennis stars. He's landed a bit part in "Expendables 2," which is now filming. Djokovic plays himself in the film, which was shot in Bulgaria. The movie stars Liam Hemsworth and Jason Statham, along with a number of Hollywood legends, and is set to be released in 2012.

Has the "Djoker" got the chops? Well, a parody of a Maria Sharapova commercial for Head racquets was so popular, Djokovic was hired by the company to make a legitimate spot with Sharapova.

While acting seems like a fun career, he doesn't need the money. Djokovic has made more than $23 million in prize money. He's third all-time in career earnings, according to the Tennis Channel.

The Chicago Sun-Times reports the tennis ace has informed friends he hopes to become a full-time actor when he hangs up the tennis shoes.
