Sheen was not a big time producer or director so not him. PLus he was 25 at the time.

Couldn;t be Downey. When Haim a kid, so was Downey to a certain degree and didn;t wield that much power at that time

Never Tom Hanks, wasn;t a director or ever around those guys. John Travolta comes to mind. Tom Hanks to busy as an actor. David Geffen? Jeff Katzenberg? My guess is Harvey Weinstein
