Morgan once again paired with actor Michael Sheen for the 2008 adaption of his play, Frost/Nixon. Sheen plays British talk-show host David Frost and Frank Langella plays former President Richard Nixon as they reprise their stage roles for the 2008 film version directed by Ron Howard.

Mogran was nominated for a Best Adapated Screenplay Oscar for his piece, but the award went to Simon Beaufoy, writer of Slumdog Millionaire.

• Regarding selecting Ron Howard to direct Frost/Nixon: "I just feel that if I'm English and writing about an American president, I have got to have someone on my side who can help me out when I'm lapsing into lazy or obvious European scepticism."—Peter MorganMetro: Clooney Wanted to Direct Frost/Nixon (December 1, 2008)

• "It's refreshing to have a writer write for an actor instead of a director. It's like a composer writing for a player instead of a conductor."—Michael SheenVariety: Variety Award: Michael Sheen (November 20, 2008)

• "Peter writes very human characters. Culture today tends to ostracize as well as worship celebrity and power. I think we all feel a bit alienated from it, the political process and the celebrity world. By humanizing these characters in a way that we can relate to as opposed to showing their flaws just to pull them back down to size, Peter makes us feel like we're all a part of the same thing. That's why I enjoy doing the stuff that he writes."—Michael SheenVariety: Variety Award: Michael Sheen (November 20, 2008)

• "His films have essentially the same two characters. One is young, slick, likable and wildly ambitious, often underestimated as a lightweight solely obsessed by celebrity or personal gain. The other is older, more experienced and accomplished, unpopular or socially awkward, but often with a vulnerability that we find surprising appealing. In the end, the younger man tends to emerge victorious, but often having shown more mettle and depth than we'd imagined, while the older character often arouses our sympathy, even in defeat."—Los Angeles TimesLA Times: The Man Behind Frost/Nixon (November 24, 2008)
