Trivia

First American film to credit the stunt people in the credits (first British film to do so was the James Bond film Moonraker (1979)).

The fender bender Judy causes as she crosses the street to the Bristol Hotel was added on the spur of the moment. When no stunt cars were available, Peter Bogdanovich instructed a crew member to rent two cars and make sure he got collision insurance. Then he staged the wreck before returning the battered cars.

Ryan O'Neal parodies one of his earlier performances. At the end of the movie, Judy Maxwell says, "Love means never having to say you're sorry," (a line from Love Story (1970)), to which O'Neal's character, Howard Bannister, replies, "That's the dumbest thing I ever heard." They added a pause cross cut because the laugh was so loud after Judy's line that Howard's line could not be heard.

The final chase scene, a spoof of the one from the then recent movie Bullitt (1968) which was also filmed in San Francisco, cost $1 million to shoot (a quarter of the total budget), 19 days to shoot requiring 32 stuntmen resulting in 11 minutes of screen time. The segment with the giant pane of glass alone took four or five days to film. The plate glass bit was filmed at the junction of Balboa and 23rd Avenue in San Francisco's Richmond District.

When Howard Bannister ends up at the rooftop cocktail lounge, which was under construction, it was not a set, but actually the "Starlight Roof" of the Hilton, which was being remodeled at the time. The view of San Francisco is the actual view from the room. A piano was brought up and placed in the room for the shot. Barbra Streisand sang the song live, not to a recording, because director Peter Bogdanovich wanted her singing to sound natural as she stepped down from the top of the piano.
