'Wolf of Wall Street' Broker: Hey Leo, Quit Dodging My Lawyers

Leonardo DiCaprio's too busy jet-setting around the world to sit for a deposition ... at least according to the guy suing Martin Scorsese and Paramount for his portrayal in "The Wolf of Wall Street," -- and now he wants a judge to tell Leo he's gotta show up to get grilled.

According to legal docs, Andrew Greene, an ex-business partner of Jordan Belfort -- the real 'Wolf' -- says he'll fly to L.A. to meet with Leo if that's what the actor needs.

According to the letter, the studio's lawyers claim Leo's got a busy schedule and instead they've offered another witness -- an executive from the actor's production company.

Andrew's lawyers say that won't cut it, saying they've already deposed Scorsese, and the movie's screenwriter, Terence Winter. Now they want Leo.
