Blake's 7

Orbit - S4-E11

Character mistake: Whilst brutalising Pinder, Egrorian asks if he can feel his humerus grinding against his radius, but the bones in the forearm are the radius & ulna. The humerus is the single bone from the shoulder to the elbow.

Headhunter - S4-E6

Character mistake: Tarrant says they can't land the ship without Slave. Yet in 4-1 "Rescue" he questions the competency of the automatic systems and offers to land the ship himself.

Rescue - S4-E1

Character mistake: When discussing Ensor, Avon says he'd spent 20 years of his life in hiding. Yet in 1-13 "Orac" Blake said he hadn't been seen for 40 years.

The Web - S1-E5

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)

Trivia: After a homicidal Avon failed to find Vila aboard the shuttle, footage in which Vila emerged in tears was cut from the final version of this episode. (Only a few seconds of it remains.) The emotional scene was deemed "too intense" for the younger viewers.
