Trivia: A clever, subtle hint as to Mason's guilt - Columbo arrives at the animal pound just in time to stop him feeding Laurel and Hardy (the dogs he trained to kill on command) a large amount of chocolate treats. He has planned this murder meticulously, and he would be aware that chocolate is extremely toxic to dogs. The amount he is planning to feed them from the bulging bag of large chocolate balls he is holding would kill both dogs within hours if ingested.
Trivia: Johnson's script originally featured an ending in which Jesse loses the game and yet finds himself still alive. Seeing this, Fats explains that he will die "as all second raters die: you'll be buried and forgotten without me touching you. If you'd beaten me, you'd have lived forever." This ending was eventually filmed when this episode was remade in 1989, during the first revival of The Twilight Zone.
Trivia: The initial footage of the episode was taken from the movie Airport 1975 (a Columbia Airlines jumbo jet). (00:00:01)
Trivia: Tommy has been more colours than any other Ranger. He has been the Green, White, Red, and Black Ranger.
Trivia: The original ending of the episode would have Norma pressing the button and getting the money after Arthur dies in a train accident. When Norma asks the stranger why Arthur had to die, the stranger responded, "Did you really think you knew your husband?"
Trivia: (POSSIBLE SPOILER) When Masuka brings up the list of doctors authorized to get the M99, Dexter removes his alias note that Dexter's fake alias (used to get the M99 tranquilizer) is Dr. Patrick Bateman. Patrick Bateman is the lead character of "American Psycho". This was most likely an intentional "easter egg" of sorts within the show.
Trivia: Throughout the show, the number 47 appears many times. There are multiple room 47's (where Syd found the Circumference in season 1 and the room in her memories from season 3, among others.), there are 47 Rambaldi artifacts, and Page 47 of the Rambaldi manuscript was the page that had Sydney's picture on it. Also the pagers flash 47911 when they get called into the office.
Trivia: At the end of the episode, Superman believes that Lex Luthor died after giving the Anti-Life Equation to Darkseid, who also vanished along with Lex while the others believe that Lex is still alive, and they might see him again. According to Dwayne McDuffie, Lex Luthor and Darkseid became a permanent part of the source wall when they solved the Anti-Life Equation. The same fate that happens to anybody who solves it.

Trivia: Edward James Olmos (Commander Adama) plays a man involved in a search for dangerous androids who are nearly impossible to distinguish from humans. He played a man in a very similar situation in Blade Runner as Gaff. Amusing coincidence.
