This "American Masters" PBS special focuses on the life and legacy of Johnny Carson. An intensely private man whose guarded personal life was a sharp contrast to his gregarious on-screen persona, Carson brought laughs to millions during his 30-year stint as the host of "The Tonight Show." Through classic footage and interviews with David Letterman, Jay Leno, Jerry Seinfeld, Doc Severinsen, and others, this documentary spotlights the man behind the entertainment. 120 min. Widescreen; Soundtrack: English Dolby Digital stereo; Subtitles: English (SDH).
