Visible crew/equipment: After Doctor Ellingham finds the sofa on the road, Bert shows up and sits down on it and talks. As he does, watch the side mirror when Doctor Ellingham returns to his car. When the door opens, you see the reflection of a cameraman or other crew member reflected in the mirror. (00:02:05)
Continuity mistake: Dr. Dibbs puts a chair to block the treatment room door, then bails through the window, Doc Martin and her husband go around the house to intercept her, followed by all in the waiting room...yet, when Doc Martin returns to the treatment room to examine a patient's injured arm, the door is miraculously ajar.
Character mistake: Dr Ellingham makes two character mistakes in short succession in this episode. First, in the bedroom scene with all in attendance, he calls Mrs Dunwich 'Mrs Winchelcy'. Then, when attending to Morwenna's Grandfather William in his garden he calls him "Mr Dunwich." Apparently his character name is William Winchelcy and not William Norcross (Morwenna's surname).
