Continuity mistake: When the fire starts in the bus depot, the manager tells Stan to reverse the bus away from it, and ends up crushing Blakey's minivan. The van changes from a Morris model to an Austin model, just before it is crushed.
Continuity mistake: When Arthur and Olive go upstairs for an 'early night' and Arthur finds the tennis balls sewn on the back, Olive calls Mum upstairs when he complains. Both Mum and Stan then come upstairs all dressed ready for bed, when they were just downstairs in their normal clothes.
Suggested correction: There was an unseen passage of time. This is evident from the fact that Olive now has curlers in her hair, a face mask on, and is also in her pyjamas. Arthur has also had enough time to remove his work uniform and put his pyjama bottoms on. This would have been more than enough time for both Stan and his mum to come up to bed themselves and get changed.
Continuity mistake: At the darts match, Arthur's clippie Nora is wearing white boots. But when she's fighting with Olive, her boots have changed to black. Then after the fight they are white again.
Continuity mistake: Before the opening titles, Stan is upstairs with a clippie on a closed top bus. When Jack is next to the bus with passengers you can see sunlight shining in the stairs indicating an open-top bus.
