If Charlie Sheen doesn't "straighten up," he will NOT star in the upcoming "Major League" movie ... because the man in charge of the flick tells us he doesn't want another Lindsay Lohan situation.
TMZ spoke with James G. Robinson -- CEO of Morgan Creek Productions -- who tells us, "I'm not going to risk putting Charlie in the movie if he continues messing up."
Robinson continues, "Obviously with Major League 3 there's a huge part written for Charlie's character ... but after dealing with Lindsay Lohan on 'Georgia Rule,' I can speak for someone who has experienced the difficulties of working with an actor dealing with addiction."
"I won't go through that again. If Charlie doesn't straighten up ... I unfortunately can't put him in the movie."
Robinson explains, "When Lindsay was doing 'Georgia Rule,' she would miss full days of work. When an actor doesn't show up for work, you can lose half-a-million dollars a day paying the 250 other people there for the shoot and the costs for the set."
"Two and a Half Men" was officially shut down for the rest of the season after TMZ reported that Charlie wanted to challenge the show's creator Chuck Lorre to a cage fight.
