HBO just announced that the two-part documentary, titled The Zen Diaries of Garry Shandling, is slated to debut Monday, March 26th and Tuesday the 27th. Some of the documentary’s special guests include James L. Brooks, Jim Carrey, Jay Leno, Conan O’Brien, Sarah Silverman, Jerry Seinfeld, Sacha Baron Cohen, Kevin Nealon, and Bob Saget, plus “four decades’ worth of TV appearances, along with personal journals, private letters and candid home audio and video footage that reveal his brilliant mind and restless soul.†Here’s more from HBO’s press release:
 “Give what you didn’t get,†wrote Shandling in a journal late in his life, the mantra of a self-proclaimed “spiritual warrior†still challenging himself to transcend his own insecurities, despite achieving so much in the face of loss, betrayal and tragic twists of fate. From childhood tragedy to heartbreak, professional betrayal and unexpected physical trauma, to his emergence as a powerful teacher, friend and guiding spirit for a new generation of talent, Apatow’s documentary not only chronicles one man’s ability to survive the ups and downs of a life in show business, but also offers a profound investigation into the power of comedy to elevate the human spirit.
