Both the film and the play take dramatic license with the on-air and behind-the-scene details of the Nixon interviews. Jonathan Aitken, one of Nixon's official biographers who spent much time with the former president at La Casa Pacifica, rebukes the film for its portrayal of a drunken Nixon making a late-night phone call as never having happened. Ron Howard discussed the scene on his feature commentary for the DVD release, pointing out it was a deliberate act of dramatic license, and while Frost never received such a phone call, "it was known that Richard Nixon, during ...the Watergate scandal, had occasionally made midnight phone calls that he couldn't very well recall the following day." Elizabeth Drew of the "Huffington Post" and author of "Richard M. Nixon" (2007) noted some inaccuracies, including a misrepresentation of the end of the interviews, the failure to mention the fact that Nixon received 20% of the profits from the interviews, and what she says are inaccurate representations of some of the characters. Drew points out a critical line in the movie that is particularly deceptive: Nixon admitted he "'...was involved in a 'cover-up,' as you call it.' The ellipsis is of course unknown to the audience, and is crucial: What Nixon actually said was, 'You're wanting me to say that I participated in an illegal cover-up. No!'"
