Best TV mistakes of 1987
Continuity mistake: In episode 10 (Joey's Place) the Tanner family move Joey into the garage, redecorating it so the entire place is filled with Joey's furniture, but in episode 12 (Our Very First Promo), it shows the characters in and out of the garage which is completely empty and back the way it was before Joey moved in. Later in the episode Joey's stuff is out of the alcove again.
Continuity mistake: Brooke and Ridge have known each other for at least 3 years when Rick is born. Yet when Rick is 16 Brooke and Ridge talk about how it's been ten years since they met. Even given soap opera children's amazing ability to grow it's a huge mistake that they say they've only known each other ten years when it's at least nineteen.
Continuity mistake: When Catherine enters the precinct station, the desk sergeant places a small white file box on the counter. There's nothing else sitting next to this, but when the shot reverses, a tall black police radio with an antenna sticking up has appeared there.
Visible crew/equipment: Series 19, "Pandamonium": When Paul and Barry are trying to find the panda, Barry (dressed in a panda costume) thinks he is looking at his own reflection. You can see the camera and cameraman reflected in the mirrors, and you can also see people watching the scene being filmed.
Factual error: David Jason's character visits the bank to pick up the share certificates left to him by a previous Master. Much to his surprise the bank manager tells him that these shares are now worth £500,000. The bank manager looks at the certificates, then at a screen by his desk before making the calculation very quickly in his head. Given that the certificates are decades old this is impossible. It would take a considerable amount of time to work out the new number of shares that the certificates would entitle the bearer to based on share splits and consolidations over the years. Also, the shares would be denominated in pre-decimal currency so they would have to be revalued based on the conversion rate at the time Britain went decimal. It would be a time consuming and painful task to decide their new value.
