Kurt Cobain: Montage of Heck. Brett Morgen, who profiled film super-producer Robert Evans in the fantastic documentary The Kid Stays in the Picture, looks at the life of Nirvana frontman Cobain, with the full participation of Cobain's widow, Courtney Love, and former bandmate Krist Novoselic. The doc humanizes the rock god, showing the man behind the myth. 9 p.m. Monday on HBO.

David Letterman: A Life on Television. Ahead of Letterman's farewell show on May 20, comedian Ray Romano hosts a look at the career of the last of the late-night greats. 9:30 p.m. Monday on CBS.

Inside Comedy. Tonight Show regular David Steinberg hosts this documentary series interviewing comedians from film, television, and the stage. The fourth season includes interviews with part-time Media resident Wanda Sykes, heir to the Late Night throne of Stephen Colbert, and recent Academy Award nominee Michael Keaton. 11 p.m. Tuesday on Showtime.

Fake Off. Two Philly Fringe Fest favorites - Brian Sanders' Junk and Tribe of Fools - compete on TruTV's reality show pitting next-level troupes that combine theater, acrobatics, dance, and technology to create iconic pop-culture moments. 10 p.m. Wednesday on TruTV.

Grace and Frankie. Lily Tomlin and Jane Fonda reunite for Netflix's new comedy. Grace and Frankie (Fonda and Tomlin, respectively) are two very different women thrown into a new life together when their husbands (Martin Sheen and Sam Waterston) declare their love for each other. Fingers crossed for a Dolly Parton cameo. All 13 episodes stream on Netflix on Friday.
