The shot of Clarissa contorted in bed was achieved using Devin DeVasquez and one of DeVasquez's friends, who was buried under the covers with her legs exposed. The two were placed at such an angle that it appears to be Clarissa's body twisted in a strange position.
Towards the end of the movie Bill goes home to confront his parents. When looks out the window and sees their car pull up it's night, but when he goes down stairs to greet them it's suddenly day.
When Clarissa squirts the suntan cream on Bill's face on the beach, it is in a different pattern in the next shot, and lotion smeared on his shoulder disappears between shots.
What are the differences between the VHS from Republic and the unrated DVD from Anchor Bay?
A
Before its DVD release Society was only available as a R-rated VHS with a running time of about 94 minutes. With the appearance of the Anchor Bay DVD fans got the chance to see the unrated version of Brian Yuzna's dark satire that runs approx. 4 and a half minutes longer than the old VHS. Most of the new scenes are story extensions but there are also some more violent frames. A detailed comparison between both versions can be found here.
