DVD: Frost / Nixon, For retail and rental, (Universal)

Ron Howard's Oscar-nominated film of Peter Morgan's play dramatises the events which led up to David Frost's televised interviews with Richard Nixon in 1977.

It's a deliciously witty comedy-drama, and Michael Sheen and Frank Langella are splendid in the title roles. But it doesn't quite add up to the David-and-Goliath clash the film keeps promising us, nor does it pin down why Sheen's oily chancer would have any more luck with Tricky Dicky than his previous inquisitors.
