Factual error: Part 4: The cord on the telephone Pug uses to call Pam should be a straight wire. Instead, it's coiled: a design not yet in use in the 1940s. (00:13:30)
Continuity mistake: In the scene where Neville is telling Dennis he should find a woman, Dennis is getting dressed up in his suit to meet Dagmar. After Neville has finished talking, Dennis leaves the hut without a suitcase. But when he arrives at the hotel with Dagmar he is seen putting his case on the bed(Dagmar has one as well). It is clear that he has come straight from the hut, as he is telling Dagmar what Neville had told him before he left.
Continuity mistake: When Ryo tells Roberto that a drunkard like him is unfit to be the coach, next to him there's someone with an orange jersey, but there's nobody wearing that color in the wider shots. (00:21:10)
