This location was also used for the Long Island Mansion "Somerton" scenes where Bill finds women wearing masks and scanty underwear.

This location provides the backdrop to some of the Long Island Mansion "Somerton" scenes Bill finds women wearing masks and scanty underwear.

Whilst Knebworth did not appear in the final cut, there was a scheduled scene that was due to shoot in the Library involving a snooker table in the centre and a cast member in a state of undress upon the table. As the actors took up their positions, it came to light that the actress involved had not agreed to the scene in question and refused to take part. Consequently whilst Knebworth House benefited from the location fee from the production, the shoot did not actually take place and the entire cast and crew departed!

Bill and Alice attend a Christmas party at the home of Victor Ziegler (Sydney Pollack), a friend and patient of Bill's, a wealthy attorney. During the party, a Hungarian man (Sky du Mont) tries to seduce Alice, while two younger models try to seduce Bill. Alice and Bill both resist temptations because they are married. During the party, Bill is summoned by Ziegler to his private bathroom where he finds a naked woman. Ziegler had been partying with an escort, Mandy (Julienne Davis). When she shot up a mixture of heroin and cocaine, she passed out, scaring Ziegler. Bill rouses her back to consciousness then talks to her about getting into rehab. Ziegler makes Bill promise not to mention the incident to anyone. Bill also meets an old friend, Nick Nightingale (Todd Field), a former fellow student who dropped out of medical school and is now a pianist at the party. Nick informs Bill that he is playing at the Sonata Café and tells him to come see him at another gig.
