What’s the hold up on Men in Black III? Will Smith doesn’t like the script.
Shooting on the big threequel has been delayed because its lead star wants to see some changes, according to the new issue of The Hollywood Reporter (now on newsstands).

Though the script’s original draft (penned by Tropic Thunder writer Etan Cohen) found favor with the studio, Sony Pictures, director Barry Sonnenfeld and producer Walter Parkes, Smith wasn’t wild. “He’s become very enamored with aspects of screenwriting,” says a source involved with the production.
Nevertheless, in an unprecedented move, Sony started shooting in November — with only one act of the script completed.
