A Charlie Brown Thanksgiving (1973)

Continuity mistake: As Charlie Brown, Patty, and Marcie are talking, the grandfather clock strikes four. Trouble is the pendulum is stuck in place, first on one side, then the other. It doesn't swing.

Movie Nut

Continuity mistake: When Snoopy brings the food to the table, there are only napkins and plates. When Peppermint Patty says grace, food appears on the table.

Continuity mistake: When Snoopy first goes to his doghouse it's in the middle of an open field. Later when he gets the turkey out it's sitting next to 2 trees.
