Frankie Muniz ("Malcolm in the Middle") is attached to an untitled bachelor party project at MGM, reports Variety.
He will play a decidedly inexperienced younger brother who must plan the big night of illicit fun for his older sibling after the best man is jailed and unable to perform the task.
MGM snapped up the pitch from the writing team of Andrew Jacobson and Adam Jay Epstein ("Not Another Teen Movie") for a low-six-figure advance.
