Chronology of '7 Thieves' and 'Ocean's Eleven'
Both "robbery planned by gang" films were released the same year (1960), but "Seven Thieves" was first. It was in production from late July '59 to late October '59, then was released on March 12, 1960. "Ocean's Eleven" (original, with Sinatra and Dean Martin) was in production from mid-January to mid-March '60, and was released on August 10, 1960, five months after "Seven Thieves." -- Prof Steven P Hill, Cinema Studies, University of Illinois.
