Memories of Cab 804 (2) - S1-E12
Revealing mistake: The gang is talking about their experiences in Cab 804 but when Elaine's segment begins, Tom Selleck gets in the cab and the cab number is 264.
Revealing mistake: The double-bladed axe one of the Decimas uses to attack the station windows is wobbling as he strikes with it. Small wonder he's not getting far at breaking in, with a weapon made of rubber. (00:22:30)
Saga of a Star World (1) - S1-E1
Revealing mistake: In the second shot showing the fleet of Battlestars (from the port side and slightly behind), two ghostly images fly in formation with the three Battlestars shown. They are just above the closest ship (where the narrow middle meets the larger rear section). It seems that the shot may have originally contained 5 ships and an attempt was made to 'remove' the most distant two, leaving the "ghosts". (00:02:45)
Revealing mistake: When Adler fights with David close to the detonator just before his second transformation, the shots are filmed too close. It makes it really obvious that a stuntman is replacing David for most of the fight.
Revealing mistake: At the start of every episode, during the credits, you can see the shadow of the helicopter filming the aerial scenes.
Revealing mistake: When Mork rollerskates into the wall, the wall moves slightly.
Revealing mistake: When they switch over to a rock format at the station, Dr. Johnny Fever puts on the first record and sets up the needle. The needle then proceeds to ride across the entire record when it starts to spin all the way to the center of the record.
Revealing mistake: When Freddie is on his bunk listening to his Walkman you can hear the music, but you can see that there is no cassette in the Walkman.
