Factual error: When Ewan McGregor's young wife is hanging clothes in her backyard, a small digital satellite dish is visible on the rooftop of one of the houses in the background. This isn't something that should seem out of ordinary, except for the fact that the events in the scene were supposed to be taking place during the Korean War. These dishes weren't commonly seen on rooftops until the mid to late 90s.
Factual error: As Jenny Hill is signing over the deed of her land and house to Edward, you can see that the recording location (Volume, Page) is filled in. Also, the County Clerk's seal has been applied at the bottom of the document. In truth, this is the last step. The County Clerk will never see this document until all signatures have been gathered, and only at that time will the recording location be known.
