This is a documentary about an unfinished movie. Frank Zappa and the Mothers of Invention try to film the sci-fi epic "Uncle Meat."

Produced by Frank Zappa in 1982, The Dub Room Special combines footage from a performance at the KCET studios in Los Angeles on August 27, 1974, a concert performed at The Palladium, NYC on October 31, 1981, some clay animation by Bruce Bickford, and several interviews. Previously only available through mail-order, it was made widely available on DVD on October 17, 2005.

in 1982 there was a boy like you who loved the Beatles and the Rolling Stones but most of all he loved Frank Zappa.... that boy was me and today 30 years after the concert at the Palermo stadium finished amidst police tear gas, I retrace Frank Zappa's journey to Palermo and Partinico, the city from which his father and grandfather left for the USA at the beginning of the 20th century. Now Frank's children, Dweezil and Diva, are going to Sicily for the first time, together with Massimo Bassoli, a friend of Frank's, who had accompanied him in 1982. It is a journey towards their Sicilian origins .... (Salvo Cuccia )

An American Dissident: un tributo a Frank Zappa is an Italian documentary that aired on the Videomusic channel on January 7, 1994. It includes footage from Zappa's Universe, Video From Hell, Does Humor Belong In Music?, Baby Snakes, The True Story Of 200 Motels, The Late Show, Zappa's May 17, 1988 show at Palacio de Deportes in Barcelona, Spain, The Dub Room Special, various other interviews and performances.

In the feature documentary, Summer 82 – When Zappa Came to Sicily, filmmaker and Zappa fan Salvo Cuccia tells the behind-the-scenes story of Frank Zappa's star-crossed concert in Palermo, Sicily, the wrap-up to a European tour that ended in public disturbances and police intervention. Cuccia had a ticket to the concert but never made it. Thirty years later, collaborating with Zappa's family, he re-creates the events through a combination of rare concert and backstage footage; photographs; anecdotes from family, band members, and concertgoers; and insights from Zappa biographer and friend Massimo Bassoli. The story is also a personal one, as Cuccia interweaves the story of Zappa's trip to Sicily with his own memories from that summer.
