and ending scenes were filmed at the San Francisco International Airport (SFO) in the South Terminal (now Terminal 1). The opening scene was filmed in the downstairs TWA Baggage Claim area, and the next to last scene was filmed in the upstairs departure area beneath the arrival/departure board and at the flight insurance counter. The San Francisco Hilton was the shooting location for the Bristol Hotel. The exterior of the hotel, where Streisand is hanging from a ledge, was shot in Westwood, Los Angeles. The San Francisco setting was chosen to allow an elaborate comic spoof of the San Francisco car chase in the hit 1968 film Bullitt. Bogdanovich claims the rousing chase sequence accounted for one-fourth of the film's $4 million budget. The classic "plate glass" scene, in which O'Neal and Streisand are pedaling on a stolen grocery store delivery bicycle, was filmed at Balboa and 23rd Avenue in the Richmond District. In another scene, their out of control bike goes down Clay Street in Chinatown. The Volkswagen Beetle is stolen from the curb in front of Saint Peter and Paul Church at Washington Square Park, and the Beetle hides on a car carrier on Sacramento St. just west of Van Ness Avenue, in an area where many car dealerships were once located (Van Ness was San Francisco's "Auto Row"). The production did not have permission from the city to drive cars down the concrete steps in Alta Plaza Park in San Francisco; these were badly damaged during filming and still show the scars today. At the end of the car chase, almost everyone ends up foundering in San Francisco Bay—except O'Neal and Streisand, comfortably afloat in their Volkswagen Beetle. During the making of this scene, the actor Sorrell Booke almost drowned in the Bay. The final scene on board a TWA Boeing 707 shows O'Neal looking out the righthand window showing the Marina District and the Embarcadero Freeway. Music Although What's Up, Doc? is not a musical, it contains some singing and other musical moments. The song "You're the Top" from the musical Anything Goes is sung as a solo during the opening credits by Streisand, and as a duet during the closing credits by Streisand and O'Neal. The same Cole Porter musical supplied at least two other tunes played as background music: "Anything Goes" and "I Get a Kick Out of You", heard during the first hotel
