After preview reactions, director Sydney Pollack took out a sequence of several scenes from the movie's climactic turning point, most notably: (1) a highly emotional scene where Katie drives through UCLA and stops to watch a young woman hold a political speech, reminding Katie of herself 20 years ago (2) a dialog between Katie and Hubbell where he tells her that someone has informed on her. Having a "subversive" wife, it's clear that (unless she would inform, too) he will be fired.
The college scenes were shot at Union College in Schenectady, New York. The large rotunda-like building is the Nott Memorial at Union College. The restaurant scene where Robert Redford and Barbra Streisand meet outside was filmed at the old Medberry Hotel in Ballston Spa, New York.
The segment dealing with the McCarthy witch hunts had much more screen time. However the segment was cut to the bone. The chief victims of the cuts were Viveca Lindfors and Murray Hamiltion whose roles were turned into brief bit parts.
