Other mistake: When Harry spits baby food on the baby (the camera lens in actuality) in retaliation for the baby spitting food on him and Tommy, Joseph Gordon-Levitt breaks character and laughs uncontrollably and looks at and gestures to off-screen crew members a couple times. (00:06:25)Phaneron
Continuity mistake: When Jennifer comes into work the next day after her dinner date with Dick, her face is covered in hives from an allergic reaction. Later when Dick interrupts her choral group, the hives on her face have disappeared. She and Dick are wearing the same clothes in both scenes, so she couldn't have overcome such a reaction in such a short amount of time. (00:12:30 - 00:15:00)Phaneron
Trivia: When the Solomons meet the Big Giant Head at the airport and ask how his flight was, he says that it was horrible because when he looked out the airplane window, he saw something on the wing of the plane. Dick responds that the same thing happened to him. William Shatner appeared in the 1960's Twilight Zone episode "Nightmare at 20,000 Feet" in which a gremlin tried to destroy the wing of a plane. John Lithgow appeared in "Twilight Zone: The Movie" playing the same character in the same situation.
Trivia: Dick is never seen walking in this episode and is only in an upright position when he moves from the chair in the lounge room to the wheelchair in the opening scene. This is because John Lithgow hurt his ankle playing tennis, and the episode was written to allow him to be in a wheelchair for the entire episode.Douglasac
Dick: Does anyone remember why we all decided to be white?
Harry: Oh, um, I went with white ‘cause I thought it'd be a little cooler in the summer.
Tommy: Well don't you remember, Dick? All the television signals that we picked up in outer space were filled with white people.
Sally: Oh, except for that, uh, that black nerd with the hiked-up pants and the oversized glasses. What was his name?
Tommy: Bryant Gumbel.
