Mullen was working with Blackie Dammett on the Chili Peppers biography, Red Hot Chili Peppers: An Oral/Visual History when he died suddenly after suffering a stroke in 2009 and was unable to complete work on the book though it eventually was finished by Mullen's long-time companion Kateri Butler and designer/musician John Curry, who had been friends with Brendan since the Masque days and was a member of The Flyboys.
He made friends with Marlon Brando and Blackie Dammett, Anthony Kiedis's father, and had a small part in A Streetcar Named Desire (1951).
