This was the first time real-life mother and daughter Markie Post and Kate Armstrong Ross had ever acted together.
The length of time from conception to shooting was 64 days.
Markie Post's makeup was partly inspired by an unused makeup Dick Smith did on Karen Black for Burnt Offerings (1976). Rick Baker got the reference on set right away.
Director Dave Elsey and actor Rick Baker jointly won the Academy Award for Best Makeup for The Wolfman (2010)
