How much (if any) did Don Coscarelli direct?
Question is in the title. IMDB amongst others says he quit before production, other sources (including wikipedia) says he was the one who started shooting without the werewolf costume and was then replaced later by Daniel Attias.
The only mention I could find in an interview as Coscarelli saying that after his experiences on Silver Bullet he wanted more control. Which is pretty inconclusive
I'd like to think he shot the bullet making sequence, which would explain why it looks so much better then the rest of the picture
