Wesley Willis: The Daddy of Rock 'n' Roll is a 2003 documentary film directed by Daniel Bitton about rock musician and artist Wesley Willis, who died four months after the film's release at age 40.

Willis, challenged by a weight disorder as well as paranoid schizophrenia, is followed in his daily tasks, trials and tribulations in autumn 2000, showing him writing his unique yet virtually identical songs, playing a show, attending to daily chores, and working on his ink paintings at Genesis.

His songwriting technique is shown as he visits a local Kinko's dressed sloppily and barefoot, and types expletives and repetitive bestiality references on a computer as lyrics and prints the document.

His songs deal with subjects such as praise for celebrities that he had met or admired, reports on bands that he had seen, stories about violent confrontations with superheroes, and expletive-packed rants at his mental demons.

Willis says music helps him silence the discouraging mental voices, but his fan following comes from people who find his songs humorous.
