Visible crew/equipment: When Leatherface is chasing Jenny, she gets into a couple's caravan. After Leatherface tries to get in, it cuts to an exterior shot and as Leatherface is running along with the caravan, in the window behind him you can see a crewmember with a cap on, running behind him off-screen.
Continuity mistake: When Jenny is hiding in the trees all out of breath, after Vilmer drives off in his truck, the left shoulder strap of Jenny's prom dress is up on her shoulder but then in the next shot it has fallen down her arm. In the following shot it is back on her shoulder! Also there is a flowery corsage on her dress which is on top of a bow which is part of the dress; but in the next shot the corsage is under the bow, then back to being on the bow in the final shot.
