Revealing mistake: When Richard first wakes up after travelling through time, he's supposed to be lying on a couch. Yet there is a wall behind him. It's blatantly obvious that it's the same shot from the modern bedroom, and all they did was change the lighting. (00:33:45)






Answer: Because they had met before. When Richard went back in time to 1912, Arthur was a five-year-old boy. Old Arthur remembers, or at least recognizes, Richard from that time.

Except that Richard hadn't travelled into the past yet.
Like all time-travel fiction, if he will, then he already did. The portrait he saw in the gallery of Jane Seymour is another example: He brought the smile to her face and IIRC, she changed her pose upon seeing him.

Exactly right. Time-travel films rarely make sense plot-wise. They employ a "suspension of disbelief" where the audience just accepts the premise so the story can be told, regardless of whether or not everything makes sense. As I recall, Jane Seymour's "old character" told Richard to "come back to her," meaning she wanted him to go back in time to when she was young.

Time Travel movies and shows do this sort of thing often. This movie actually keeps to the premise of time travel pretty well.
