When Vic is in the back of Lil's car, at night, the interior shots show the side and rear windows heavily steamed up with condensation. During the exterior shots, they are not.
It is stated at least twice that Vic Edwards was playing on the Tennessee football team during the 1951 season (supposedly a sophomore in college). However, the Wikipedia page Lil pulls up shows that Vic was born in 1936, making him 15 while supposedly playing college football. He would have been a high school sophomore during the 1951 season (in fact, Burt Reynolds was a high school sophomore during the 1951 football season as he graduated high school in 1954).
When Lil is in the hotel bathtub and she turns on the TV and googles "Vic Edwards", the IMDB link for Vic Edwards says "Burt Reynolds started off in TV westerns..."
