In an interview with "Starlog Magazine" in 2006, O'Halloran stated that he and Christopher Reeve did not get along during the making of "Superman II". On one occasion, he had Reeve against a wall, but Richard Donner intervened and dissuaded him from hitting Reeve. He later discussed this incident on the "How Did This Get Made?" podcast's Episode 24.1. Despite the clash between them, O'Halloran stated that his heart went out to Reeve after his 1995 accident, and commended him for helping others with spinal cord injuries.
