When Mr. Bean runs down the path at the park, the film of him looks reversed.
When Mr. Bean sets up his TV, his big clock shows 10:15 through the whole scene that last's at least nine minutes.
The clock also shows 10:15 when Bean packs his trunk ('Mr. Bean Rides Again'). Maybe these scenes were recorded the same day?
Two of the writers - Robin Driscoll and Howard Goodall - appear in this episode.
