Audio problem: When Young Mr. Grace arrives, the sound department misses his first "Good Morning", which is audible only very faintly towards the end. (00:15:35)
Character mistake: Mr. Lucas got himself in an embarrassing situation 'straightening the seams' of Mrs. Slocombe. Humphries passes by saving him by telling him that Mr. Granger wanted to talk to him, but he does it by saying "Griffin wants you." Wrong name. (00:07:45)
Other mistake: When Mrs. Brahms is talking to Mr. Granger, Wendy Richards' voice cracks stifling laughter when she says "Mrs. Slocombe didn't like to take down your trousers without asking you first." (00:18:00)
Other mistake: Pilot episode Mr. Lucas is holding the mannequin together with Miss Brahms. Mr. Grainger walks by and is appalled by the state of undress of the figure and says "Well, it's hardly sufficient, is it?" You can see the camera getting randomly out of focus in a bad, noticeable way. (00:03:20)
