Although the film takes place in New York, at least two sequences were filmed in Los Angeles: the scene where
Roy Scheider meets
Laurence Olivier was filmed in front of the red steps statue in downtown Los Angeles in the Arco Plaza; and the library scene where
Dustin Hoffman meets
Marthe Keller was filmed at the Doheny Library on the University of Southern California campus. Coincidentally, Hoffman filmed scenes on the same campus ten years earlier in the landmark
The Graduate (1967).
