Continuity: When Phil comes around the corner, just before meeting Ned, there are two women walking together in the background. The one in blue is holding a yellow sign upside down that says Phil (the groundhog, not the character). The first 3 days in a row they are together as they should be. On the forth day and every day thereafter the women in blue is by herself which does not follow the exact day sequences.

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.
