Corrected entry: This is a strong contender for the mistake earliest into a movie: When Charles' alarm clock rings at 9.00 the hour hand hasn't reached the set time yet (about 9.30). This happens 7 seconds after the movie actually starts, and it happens again when he gets up for the second wedding. (00:00:35 - 00:33:15)

Correction: I've had cheap alarm clocks with exactly this behaviour where the alarm goes off when the hour hand gets close to the alarm hand. That it happens twice supports the fact that it's a "feature" of the clock rather than a movie mistake. The trick to using such clocks is to adjust the time to your desired waking time and then adjust the alarm hand until the alarms sounds, then adjust the time back. In all probability the alarm clock was just set to go off anyway, rather than having the sound dubbed afterwards, so that's just how it worked.
