Continuity mistake: At the end of the movie, Frank kisses and old woman by accident during his speech. The woman disappears during a few shots and reappears on the balcony. (01:19:35)
Suggested correction: The old woman, Barbara Bush, is simply off camera standing next to her husband, George Bush. She had plenty of time to step back to be next to him when we get a shot of Jane. The balcony scene isn't a continuous shot though. And she's back because she's with George Bush on the balcony.
