Revealing mistake: Buford catches the Captain in the trailer, and instructs Junior to take the cuffs off - if you look closely, the cuffs were already undone.
Plot hole: Bandit and Snowman must have special powers to accomplish their round trip 1800 mile journey in the time they do. For starters when they begin the trip in Georgia it's sometime in the afternoon, and we later see them travelling at night before arriving at the Coors facility in Texarkana the next morning. This means the majority of their 28 hour window was spent getting TO Texarkana. So how is it they were able to both make the 900 mile trip back to Georgia while making all the stops they had to make, avoid all the smokies chasing Bandit off his path and give Bandit and Carrie time to be romantic all with only a few hours to spare after leaving Texarkana? At the very least it should have been late event or night time when they got back to their destination in Georgia.
Other mistake: The stop sign at the side road that the van pulls out from is actually facing in the direction that the Bandit is coming from and not the direction the van was coming from.
Answer: Don't know if she did cartoon voices, but her name is Nora Meerbaum. She was in Airplane and St. Elmo's fire in the following years though so you may know her from those.
I thought the same thing. Maybe one of the Mrs Clauses in Christmas cartoons.
Shirley Booth voiced the Christmas favorites.
She looks and sounds like Shirley Booth, Mrs. Claus in The Year Without A Santa Claus (1974).
