Trivia:

According to Roger Moore's autobiography, he witnessed Christopher Reeve walking through the canteen at Pinewood Studios in full Superman costume, oblivious to the swooning female admirers he left in his wake. When he did the same thing dressed as Clark Kent, no one paid any attention. Very interestingly, something similar happened with Harold Lloyd: when he wasn't filming movies and removed his iconic round glasses nobody paid attention to him at the point that no one recognized him as the famous actor he was. Lloyd was inspiration for Superman alter ego Clark Kent, specially in the detail of the glasses to hide himself of the public eye in his civilian identity.
