Charle Grodin was the "private personal confidential secretary" to
the guy whose body Warren Beatty ends up in. Remember? Grodin was
having an affair with Dianne Cannon, who played his wife. And there's
one point in the movie where Beatty sees Grodin right after Cannon
makes some funny noise in reaction to the fact that the millionaire
(who Beatty has become) isn't dead. Grodin explains that she's
reactiing to something that happened earlier. Beatty is puzzled.
Grodin says, "She relives it." I guess you had to be there.
