John Powers

A new DVD set follows the presidential campaigns of '60, '64 and '68 — and shows just how much times have changed. Critic John Powers says it's hard not to feel a bit nostalgic for the days when running for president was treated as something noble, not grubby.

The Trip, a British comedy featuring two comedians trading their best celebrity impersonations, got critic John Powers thinking about memorable voices from the movies. Famous celebrity voices, he says, are not what they used to be.

The film critic reports his impressions of this year's Cannes Film Festival. On Powers' list of notable films: Terrance Malick's Tree of Life, about a young boy growing up in 1950s Texas, and an Iranian film by a director who was explicitly told by the Iranian government not to make films.
