Too Late the Hero

Writer, producer, and director Robert Aldrich refused Cliff Robertson's request to attend the 1969 Academy Awards ceremony, as a flight from the Philippines to Los Angeles and back would be too time-consuming due to budgetary restraints. Robertson pleaded with Aldrich, even offering to pay out of pocket for any costs associated with his absence, but to no avail. Robertson won the Oscar for Charly (1968), and the crew presented him with a mock statuette made out of wood. According to Turner Classic Movies host Robert Osborne, after the Philippine location shooting was over, Academy of Motion Pictures Arts & Sciences President Gregory Peck greeted the cast as they disembarked at Los Angeles International Airport. Robertson was holding his fake Oscar when he got off the plane. As he was approached by Peck with the real statuette, Robertson threw the wooden "Oscar" over his shoulder. The fake statuette hit Sir Michael Caine in the forehead, causing him to bleed profusely.

Throughout the entire film, Lt. Lawson's wristwatch randomly moves and changes position from his left hand to his right hand and vice versa.

When originally released the US and UK versions each had a different survivor at the end of the film.
