Roger Ebert says, "the film really comes down to these two compelling intense performances, these two men with such deep needs entirely outside the subjects of the interviews." CNN calls it "a compelling account, shrewdly bolstered with lively actors in both corners of the ring". The New York Times says,
Anchored by its first-rate leads, who originated the roles on the London stage — Frank Langella as Nixon and Michael Sheen as Frost — the movie is a talkathon embellished with camera movements.Rolling Stone closes with this:
Frost/Nixon, one of the year's best films, far exceeds its roots as docudrama. It cuts to the core of a toxic culture that sees politics as show business, a culture still all too recognizable as our own.Variety describes it as
an effective, straightforward bigscreen version of Peter Morgan’s shrewd stage drama about the historic 1977 TV interview in which Richard Nixon brought himself down once again.
