 According to Bob Thomas 1973 biography "Marlon: Portrait of the  Artist as a Rebel", producer Alan Miller (I) (qv), appalled at his  stars lack of interest in the film and his lackluster performance,  pinned a bit of doggerel about Marlon Brando (qv), whose character  is called "Mateo" by his Mexican friend in the film: "Mateo, his  heart / It bleeds for the mass, / But the people he works with / He  kicks in the ass."
