 Much credit for the concept must go to its producer  Irwin Yablans (qv), who had the concept originally for a horror  film called "The Babysitter Murders". Upon further research, Yablans  discovered to his surprise that no previous film had been titled  "Halloween" and thought it would be a great concept to set these  "babysitter murders" on the holiday. With these ideas, Yablans  convinced an excited John Carpenter (I) (qv) to write and direct a  film around them.
