Story: Suspense thriller about a KRML jazz disc jockey stalked by a fan of Errol Garner's "Misty".
Scenery: Filmed entirely on the peninsula. The opening sequence shows Clint Eastwood driving up the coast from Big Sur to Carmel. KRML studio scenes were filmed at the station's original location in the Carmel Rancho Shopping Center (in the building closest to Carmel Valley Road). Brief scene of Jessica Walter having a key made outside Brinton's across the parking lot from KRML. Scenes also at the Sardine Factory on Cannery Row, a restaurant on Monterey's Municipal Wharf (now the Sandbar & Grill before the deck was enclosed), on Ocean Avenue in Carmel and elsewhere. One scene was filmed at the Monterey Fairgrounds main arena during the Monterey Jazz Festival. Donna Mills's house was on Spindrift Road in the Carmel Highlands where the climax was filmed.
Also of local interest: This was the first movie directed by Clint Eastwood, who also lives in Carmel. Eastwood's production company, Malpaso Productions, was named after a canyon in the Carmel Highlands. In 1986 Eastwood was elected mayor of Carmel and served one two-year term.
KRML is an actual radio station in Carmel (1410 AM & 94.7 FM). Although it was depicted in the film as a jazz station, at the time of the filming it actually had an easy listening format. Later it was a Christian station. KRML eventually adopted a jazz format in the early 1980s which lasted for three decades before the format changed again in 2012.
Don Siegel, who directed many of Eastwood's earlier films, played the bartender at the Sardine Factory.
