According to Jack Nicholson on a Playboy Magazine interview (April 1972), director Mike Nichols asked Nicholson and other cast members not to smoke marijuana while filming on location in Vancouver, British Columbia, where cannabis was easily available. Nichols thought that it dulled an actor's performance.

The scene in which Sandy takes out a condom while in bed with Susan was the very first time a condom was ever shown onscreen, all over Earth.

The fight scene between Jack Nicholson and Ann-Margret took a week to shoot, and at the end of it both performers had lost their voices.

Jonathan: At one time, it was great what we had... the kidding around. It can't have a natural time span. Affairs can't dissolve in a good way. There's always got to be poison. I don't see why, I really don't see why!

Bobbie: The reason I sleep all day is because I can't stand my life!

Jonathan: Why don't you leave me?... For God's sake, I'd almost marry you if you'd leave me.
