Jan Morrow (Doris Day) is a level-headed interior designer who shares a phone line with resident swinging bachelor Brad Allen (Rock Hudson). He annoys her by hogging the line with calls to his numerous girlfriends, whilst she irritates him by her refusal to accept his sweet-talking charms. Brad decides to teach her a lesson by seducing her under an assumed identity, but his plans are complicated by mutual friend Jonathan (Tony Randall), who has his own designs on Jan.
Jan Morrow (Doris Day
) and Brad Allen (Rock Hudson
) have never met, but they're sworn enemies because of one small appliance in their lives: the telephone. The two share a party line, and Jan is outraged over the amount of time Bill spends wooing women over the phone. A convenient triangle emerges when a client (Tony Randall) of Jan's--she's an interior decorator--falls in love with her and happens to be Brad's old college chum. When Brad makes the connection, he decides to try to court Jan himself, to make her more sympathetic to his phone woes. Of course, she'd never go for such a heel, so he passes himself off as Rex Stetson, a Texas rancher visiting New York. The ensuing tale, albeit predictable, is lots of fun, with some quick-witted dialogue and some clever use of split-screens for the phone calls. Thelma Ritter is hilarious as Jan's always-hung-over maid, Alma; and the pairing of Rock and Doris works beautifully, as always. --Jenny Brown
