At fifteen years old, Drew Barrymore legally emancipated herself from her parents. In 2009, she told 60 Minutes (1968) that she had first learned such a thing was possible from starring in this movie six years earlier.
Peter Bogdanovich has said in interviews that this movie is "terrible" as it makes him and Cybill Shepherd out to be the villians and presents Polly Platt as the victim in a very one-sided manner. It is ironic that Ryan O'Neal who is a veteran of several Peter Bogdanovich productions is playing the Bogdanovich character. It is also ironic that Ryan's daughter in the movie accuses him of being neglectful, since Ryan's real life daughter Tatum also accused him of being neglectful.
While the movie draws upon the Peter Bogdanovich/Cybill Shepherd/Polly Platt love triangle for its inspiration, as many critics including Roger Ebert have noted, it also draws upon Nora Ephron's "Heartburn" for much of its inspiration, as Polly Platt never wrote a bestselling novel about her husband's affair, but Nora Ephron did.
