Continuity mistake: At the end of the movie when Steve and Anna are in the boat going across the harbour, in the background is a Shell petrol station on the shore. The boat is travelling from left to right across the screen, but as the camera shots change from Steve to Anna, or both at once, the Shell sign keeps changing its relative position to the boat.
Other mistake: Near the start of the film Billy Connelly hurts his foot. He can't walk without using a crutch, but not that long after he hurts it he manages to drive without any bother. Would this not be a danger to drivers, and how can he drive so well only a short while after a sharp piece of wood has just gone through his foot?
Visible crew/equipment: At the end of the film when the cockatoo has left the building and is flying outside, you can see a wire attached to its leg.
Continuity mistake: After the cockatoo smashes the pane, it can be seen wholly intact again later.
Continuity mistake: Near the end as they are motoring through the harbour the background changes from the boats to the rocky bank and when the same angle shot is shown again it is back to the boats. Eventually they sail past the rocky bank again.
Continuity mistake: When Billy Connelly enters the stage for the TV program "Cressida", he has a bible in his hand. Just before he sits down, he puts the bible on the table. Then, after he sits down, he puts it on the table again.
