Overview
- Netflix released a first-look trailer on September 21 and says Who Is Martin Mull will stream on October 7, 2026.
- The film is co-directed by Neil Berkeley and the late Bob Saget and features producers Sean Bradley, Tara Billik and Berkeley with executive producers including Kevin S. Bright, Morgan Neville and Caitrin Rogers.
- Netflix’s official synopsis frames Mull as a musician, cult comedian, TV character actor and acclaimed painter and says the film traces his constant reinvention from folk clubs to primetime to gallery walls.
- The documentary includes one-on-one conversations with Mull along with interviews from peers such as Steve Martin, Tom Waits and David Alan Grier and uses archival material to include late figures like Fred Willard and Bob Saget.
- The film joins several high-profile Netflix comedy documentaries scheduled for October and is positioned to broaden public appreciation of Mull’s complex, decades‑long career while preserving testimony from collaborators and friends.
