First of all. There are no heroes in Hollywood. Only actors are there. Best one ? Whom will you select one of of these ? Jack Nicholson, Robert Dinero, Liam Neilsen, Dustin Holfman, Tom Cruz,Tom Hank, Russel Crowe, Brad Pit, Val Kilmer, Clint Eastwood ? Does it do any justification to all others if one of these giants is taken to be best ? There are only best there.
