Revealing mistake: In the scene were Mrs Doyle is listing the rude words and phrases used in one of Father Ted's favorite author's book's, she goes through all of them fine. Apart from the last one, when she says "Get your boll*cks out of my face" you can hear her laughing in the word "boll*cks" before she exits the room.
Continuity mistake: When Terry MacNamee is talking to Father Ted on the phone on the island, his tie is blown over his shoulder. After a cut to Father Ted, his tie is hanging straight. After another cut, it is back over his shoulder again.
Continuity mistake: Immediately before Ted and Dougal enter the fortune teller's tent, there is a scene which appears to have been shot much later in the day than those on either side - it's almost night time.
Visible crew/equipment: In the fortune-teller's tent, just as Ted chooses his second card, the boom mic enters the frame above Dougal's head.
Continuity mistake: As Father Crilly is shouting at Father Jack "No, not your room, not your room." to get up out of the spare bed, watch closely and as Father Ted strikes him in the face, notice that his hand doesn't even touch his face, and his hand stops several inches away from his face, using only his reaction and the sound of a punch to illustrate a punch at all. (00:18:15)
Revealing mistake: When Henry Sellers jumps out of the window, it's apparent that it's pre-cut glass.
Visible crew/equipment: When Dougal and Jack are on the Whirly-Go-Round, a crew member's hand can be seen on the far right of the screen spinning it around.
Answer: Ted was using his real hands to control Father Jack's wheelchair using a remote control - the fake arms were so no-one would see him cheating.
