Robert H. O'Brien (1907"1997) was a businessman and Hollywood executive who was president of Metro-Goldwyn-Mayer during the 1960s. He took over the position in the wake of the debacle of Mutiny on the Bounty (1962). Under O'Brien's regime, in partnership with head of producer Robert M. Weitman, MGM produced its last run of classic films, including Dr Zhivago (1965), The Dirty Dozen (1967) and 2001: A Space Odyssey (1968). A series of flop films saw him removed from his position in 1969.
