Laughing (not just talking) heads

Documentaries are sometimes snubbed by viewers who fear they will be a collection of talking heads introducing clips. There is some of that, of course, but modern documentaries are so much more, and here are a few new-to-DVD titles that deserve to find an audience.

"Make 'Em Laugh" (Shout, 2009, three discs, color and b/w, $34.95). This PBS program, introduced by Billy Crystal and narrated by Amy Sedaris, and which aired last month, is an overview of the past century of American comedy, from Harold Lloyd to Jon Stewart.

It's far from comprehensive, of course, and some will complain that their favorites have been overlooked, but it's fun to see the often laugh-out-loud clips and hear from some of the legends in the business, such as Bill Cosby, Dick Van Dyke, Phyllis Diller and many others, along with witty behind-the-scenes talent. And perhaps it will introduce younger viewers to some of the wonderful comedy of the past.

Extras: widescreen/full frame, extended interviews, jokes told by comics (some of which are rather racy)

"Imaginary Witness: Hollywood and the Holocaust" (Koch Lorber, 2004, color and b/w, $24.98). A fascinating observation of how American movies turned a blind eye to anti-Semitism during World War II and have tried to make up for it ever since.

Meticulously researched and edited with stirring clips from famous and little-known pictures, along with comments by filmmakers and historical experts. Narrated by Gene Hackman.

Extras: widescreen/full frame

"Blindsight" (Image, 2008, PG, $27.98). This remarkable film chronicles the amazing trek to the north face of Mount Everest by a group of blind Tibetan teens under the guidance of famous blind mountain climber Erik Weiyenmayer.

Inspiring and emotional, funny and full of the human spirit, this is a film for the ages.

Extras: widescreen, featurettes, trailer, audio-description track for the blind.

"Roman Polanski: Wanted and Desired" (Think/Image, 2008, $27.98). Whatever you think of filmmaker Roman Polanski and his flight from America after being arrested in 1977 for providing drugs to and having sex with a minor, this film will give you pause about both that case and the American judicial system in general.

It may not change your mind, but it's an intelligent investigation with comments from many involved in the case, including the victim some 30 years later.

Extras: widescreen/full frame, deleted scenes, audio commentary, bonus interviews
