Look Back was released in theaters, Pennebaker worked with author Norman Mailer (who would later appear in 1979's Town Bloody Hall) on the first of many film collaborations. He was also hired to film the Monterey Pop Festival, which is now regarded as an important event in rock history on par with 1969's Woodstock Festival. Pennebaker produced a number of films from the event, capturing breakthrough performances from the Jimi Hendrix Experience, Otis Redding and Janis Joplin that remain seminal documents in rock history. The first of these films, Monterey Pop, was released in 1968 and was later ranked at No. 42 on Time Outs list of the 50 best documentaries of all time. Other performers including Jefferson Airplane and the Who also received major exposure from Pennebaker's work. 1970s–1990s Pennebaker continued to film some of the era's most influential rock artists, including John Lennon (whom he first met while filming Dylan in England), Little Richard, Jerry Lee Lewis, and David Bowie during his "farewell" concert in 1973.

No other sessions were captured, and Pennebaker's film remains the sole episode. Original Cast Album: Company received renewed attention after being parodied in the IFC television series Documentary Now! in 2019, then being added to The Criterion Channel's streaming service the following year. In August 2021 a physical edition was released, including new commentary by Sondheim and commentary recorded in 2001 by Pennebaker, original director Hal Prince, and Company star Elaine Stritch. Pennebaker was one of many participants in John Lennon and Yoko Ono's 1971 film Up Your Legs Forever. He also collaborated with Jean-Luc Godard, who had been impressed by Primary. Their initial plan was to film "whatever we saw happening around us" in a small town in France, but this never came to fruition. In 1968, the two worked on a film that Godard initially conceived as "One AM" (One American Movie) on the subject of anticipated mass struggles in the United States – similar to the uprisings in France that year. When it became clear that Godard's assessment was incorrect,
