Mother includes a commentary by Jason Segel and Chris Harris for the episode "The Chain of Screaming". Harris, a writer on the show, did not write this particular episode, but was included in the commentary at the request of Segel, who spent the majority of the commentary intoxicated and in only his boxers. Segel at one point places 12 condoms on the table between the two and spends the majority of the commentary insinuating a relationship between him and Harris, much to Harris' chagrin. The 2000 DVD of This Is Spinal Tap features a commentary by the three members of the band, in character. They relate how they felt slighted by the film, and how the director (Marty di Bergi in the film) did a "hack job" with the documentary. The commentary is another added element to the fiction of the band. Actors Michael McKean, Christopher Guest and Harry Shearer had previously recorded a commentary for a Criterion Collection DVD which had gone out of print. Similarly, the DVD of series 1 of the BBC sitcom I'm Alan Partridge features commentary from the characters of Alan and his assistant, Lynne.

The Ultimate Matrix Collection, a box set of the entire Matrix trilogy, has two audio commentaries on each film — one by philosophers who loved it (Dr. Cornel West and Ken Wilber), and one by critics who hated it (Todd McCarthy, John Powers and David Thomson).

As the movie progresses, the group drinks and gets more and more inebriated. A similar commentary, featuring many of the participants from that commentary, was recorded for Orgazmo. The fourth, fifth and sixth season box sets of The Simpsons contain special "illustrated commentaries" on selected episodes, where two animation directors draw on screen while commenting on the episode. This is achieved by using subtitle data to produce the drawings overlaid on top of the video in sync with the audio commentary track. The Simpsons and Futurama, both Matt Groening creations, are among the few TV series to have audio commentary tracks on every episode in their season box set DVD releases. For Futurama, the commentators point out who
