Darcy DeMoss refusal to be nude
This is the only F13 film in the franchise that didn’t include nudity, a staple of the franchise and horror films in general.
Reportedly the director asked Darcy DeMoss to be topless during her sex scene because she was naked in Harbodies (1984) two years before.
But she refused even though she was naked in Reform School Girls (1986) the same year.
She then went on to perform fully nude in several erotic thrillers after this, so her refusing for F13 never made any sense to me.
Maybe it was a salary thing.
