 Doyles memorable cry of "Mickey Mantle sucks!" during the cold  turkey sequence was the source of much trouble for the film makers  and their legal department. Producer Robert L. Rosen (qv) had to  track down Mickey Mantle (qv) to obtain his permission for the  reference. After a long phone call, Rosen flew out to Mantles home  in Dallas with a print of the film, which was screened for him and  his lawyer. When Gene Hackman (qv) uttered the line, Mantle  surprised Rosen not only by roaring with laughter but also insisting  that they watched the rest of the film because both he and his  lawyer were enjoying it so much. Mantle later happily signed a  release waiver and the line stayed in the film.
