45 Years

The movie was shot in chronological order.

The morning when Rampling's character enters the kitchen, the clock reads 7:32. Later, being concerned about the passage of time, we see Rampling check her watch as she follows Courtenay into the storage area. Afterwards we see them once again in the kitchen concluding a conversation and going outside to have a smoke. To account for the time that had passed, the clock reads one hour later: 8:32. (Of course the odds are 1 in 60 that it be exactly 1 hour later, but such are the elements of master strokes!) Another morning the clock reads 8:25, and in the afternoon it reads 1:00. There are no goofs with the clock.

The opening credits play like a slide show. Every time before a new name appears on the screen, there is the unmistakable click of a slide projector.
