Brad Pitt is ready to make love to Julia Roberts — for the cameras. The two beautiful actors are about to begin filming the caper movie “The Mexican,” with Pitt telling New York’s Daily News that he’s “not worried” how their respective squeezes — Jennifer Aniston and Benjamin Bratt — might react. “Julia is really tight with Ben,” said Pitt. “And Jen and I couldn’t be better.” In the movie, Pitt plays a guy whose gun is supposedly cursed, while Roberts is the girlfriend who wants him to give up crime. As for what attracted him to the project, Brad told the News, “We’ve been looking for something to do together.” James Gandolfini, Tony Soprano on HBO’s “The Sopranos,” costars.
