Groundhog Day (1993)

Visible crew/equipment: When Bill Murray first meets Ned Ryerson, there is a reflection of the film crew very briefly in the shop window behind them.

Visible crew/equipment: After Phil drives the truck off the cliff, and it explodes in a burst of flames, there is a shot of Andie MacDowell and Chris Elliot staring in shock at the disaster. The two actors are bathed in an orange glow supposedly coming from the flaming wreckage. But in the lens of the TV camera Elliot is holding, there is a noticeable reflection of the lighting equipment used to create the glow effect on the actors.

Continuity: When Phil has the groundhog in the truck at the quarry and is about to drive over the edge, Rita's hair is disheveled and sticking out all around her head. But after Phil has driven off the cliff and she's looking down, it's all pinned neatly in place.

The screenwriters for the film have said that the total amount of time that Bill Murray is stuck repeating the same day is about 10 years.

I'm not sure if this was done intentionally, but in the scene where Phil is eating a table full of sweets, talking to Rita, as the camera pans in on Phil, there are 2 clocks on his immediate left. Both look like they indicate the same time, but one says 5:55, and one says 11:30. Notice that the angle of each hand is the same, but the little and big hands are switched. Neat trick if it was done on purpose.
