'Don't Answer the Phone'...bit cheeky!
Rather cheeky to have a "Don't Answer the Phone" poster when they're talking about other films being made to cash in on the 1st "Friday 13th".
"Phone" came out months before "F13" and owes its roots to the late 60's/70's Grindhouse Sleazy Psycho film than ANY Slasher....Certainly not one that wasn't even released yet!
