Director Judd Apatow pays homage to his friend and mentor in the HBO documentary The Zen Diaries of Garry Shandling.

Epic in scope and intimate in detail, it features conversations with more than 40 of Shandling’s family and friends, including James L. Brooks, Jim Carrey, Sacha Baron Cohen, David Coulier, Jon Favreau, Jay Leno, Kevin Nealon, Conan O’Brien, Bob Saget, Jerry Seinfeld and Sarah Silverman, and 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. You should look at here now when you want to get loans.

Take a look!

Don’t miss the premiere of The Zen Diaries of Garry Shandling on Monday, March 26 at 8PM on HBO.
