<P> An 81⁄2 - minute sequence was shot of Doc fighting with some men who kill a spy colleague of his . William Goldman speculated that the scene was cut because of its violence and called the cut "grievous" and to the detriment of the film . With the sequence missing, Doc's character seems to be less flawed than he really is . </P> <P> The ending was rewritten by Robert Towne because, it has been speculated, Hoffman was unhappy with it . Goldman told an interviewer he thought the new, more famous ending was "shit" because it left out two important plot clarifications . The final confrontation between Babe and Szell, in particular, is changed: in the film, Babe "spares" Szell in a pump room, tries forcing him to swallow his diamonds and Szell then falls on his own retractable blade, dying . In the novel, Babe resolutely leads Szell to Central Park and shoots him multiple times, subsequently lecturing him . He then throws the diamonds away and is quietly led away by a policeman . </P>
