Revealing mistake: When the 54th Mass. marches past a liberated plantation some black children wave them on. One of them is wearing a digital wristwatch.
Visible crew/equipment: When the guys walk from the deli, talking about which girl they are taking to the prom, you see a reflection in the cars parked along the side, of a crew member walking with a boom mic.
Audio problem: Much of Karen's drumming is not in sync with the drum sounds.
Continuity mistake: When Jerry goes to the plane from England to USA, the plane is white and has a TWA logo. When he arrives, the plane is silver, and the logo is one of the American Airlines.
