Continuity mistake: When a bunch of guys are out back passing around a bottle of liquor, the amount of alcohol in the bottle increases at one point.
Continuity mistake: While Troy and Bono are drinking the bottle goes from half full back to 3/4 full. (00:11:05 - 00:12:55)
Factual error: Cory comes home wearing Vietnam service and Vietnam campaign ribbons on his uniform. Those were not awarded until after 1965 and therefore could not have been awarded to Cory, who comes home around 1960.
