The Bank Job - S3-E1
Visible crew/equipment: Halfway through the show and just before the robbers make themselves known, you can see the microphone above Arnold's head for 3-4 seconds.
Diff'rent Strokes (1978)
1 visible crew/equipment mistake in season 3 - chronological order
Starring: Conrad Bain, Todd Bridges, Dana Plato, Gary Coleman
A Case of Overexposure - S5-E8
Continuity mistake: In season one episode 16, Arnold says that him and Willis never met their landlord. In this episode they remember him as Mr Darcy - when they see him they recognise who he is.
Philip Drummond: I'd better send for the limosine. Mother gets very impatient if she's kept waiting. I was born 3 days late. She didn't speak to me for a year.
Trivia: Arnold is in court and the judge asks the family how they know him. Right after Mr. Drummond says "I'm his father", Willis says "I'm his brother" and puts emphasis on "brother." The reason for this was revealed on a blooper program; in an earlier take, just after actor Conraid Bain said "I'm his father", actor Todd Bridges blurted out "I'm his son."
