Been doing a bit of digging about Nightmare of Eden and found this fact which I couldn’t help but laugh at:
According to accounts by visual effects designer Colin Mapson and assistant floor manager Val McCrimmon, Alan Bromly simply didn't understand how to direct the programme efficiently - and wasn't interested in learning. Consequently, he was removed from the project by Graham Williams in the midst of principal photography. Williams himself finished the project. Although Barry Letts had preceded Williams as an "emergency director" (for "Inferno" when the contracted director, Douglas Camfield, was hospitalised with heart problems), this was the only known instance of a producer stepping in for a director that he had been forced to fire. Mapson, a longtime veteran of the programme, flatly called it "without doubt, the most disastrous Doctor Who (1963) I've ever been involved in". When production finally wrapped, crew members were presented with T-shirts saying, "I'm Relieved the Nightmare is Over".
