Four films by French director Louis Malle, who died in 1995, have been released on DVD by Criterion. They include Elevator to the Gallows, his first feature, and a new boxed set with Murmur of the Heart, Lacombe, Lucien and Au Revoir Les Enfants. Our critic at large says that watching these films years after their release made him see Malle in a different way.

Two new documentaries probe the effects of outside influences on third-world countries. In Our Brand is Crisis, the arrival of U.S. campaign consultants threatens the outcome of a Bolivian presidential election. And Darwin's Nightmare is about the devastation of Lake Victoria in Tanzania.

Several recent DVD releases feature great black entertainers of the 20th century. For classical music critic Lloyd Schwartz, his favorites feature the great tap dance team of Harold and Fayard Nicholas.
