Pillow Talk (1959)
1 corrected entry
Directed by: Michael Gordon
Starring: Doris Day, Rock Hudson, Thelma Ritter, Tony Randall
Corrected entry: Doris Day and Rock Hudson share a party line. Tony Randall (a mutual friend of the two) is at Rock Hudson's apartment trying to get Doris Day on the telephone but keeps getting a busy signal, meaning she's using the phone. The mistake is if they're sharing a party line Tony Randall should hear her voice when he first picks up the phone.
Correction: Tony Randall is getting a busy signal but it is not because she is on the phone. It is because in order for two people who share a party line to reach each other, they need to dial a code. If they don't they will receive a busy signal. Rock Hudson's character says for Doris Day to use the code if she wants to complain to him directly.
