Observations...poss ible Spoilers **
may contain Spoilers (1) you'd think Sam & Jill would have at least agreed on where they got "married"... since they went to the trouble to have a boy with a strong British accent, where they got married should be part of their cover story. When Jill & Lea meet, Lea traps Jill by asking her if they really did get married in Paris... (2) a 3 Stooges moment during the fight down at the plant when the whole crowd is watching. is this story a comedy or a wartime sabotage film ?? (3) I DID think it was pretty light down there at the bottom of the harbor that was deep enough for a war ship when someone is rescued from the bottom . In another scene at the bottom near the end, it's lighter at the bottom of the harbor than at the top. a little inconsistent.(4) I thought it was a little unlikely that Sam would be smooching a female co-worker in daylight in front of his own house, if he's supposed to be convincing the world he is married to Jill, but I guess maybe that's just pointing out his own weaknesses. Gotta look past some of these minor glitches and just enjoy the film.
