Detective Lieutenant John McClane is a fictitious character and main
protagonist of the Die Hard film series. Portrayed by Bruce Willis, he
is known for his sardonic one-liners, including the famous catchphrase
"Yippee-ki-yay, motherfucker".John McClane was originally based on the
fictional character Detective Joe Leland from Roderick Thorp's
bestselling 1979 novel, Nothing Lasts Forever. Other aspects are
derived from Frank Malone from Walter Wager's 1987 novel 58 Minutes
(adapted as Die Hard 2).Die Hard villain Hans Gruber describes him as
"just another American.... who thinks he's John Wayne," to which
McClane replies that he "was always partial to Roy Rogers." He is
described as being a "foul-mouthed, wisecracking, no-nonsense New York
cop with an itchy trigger finger ... and a never-say-die maverick
spirit."McClane's marriage is in a constant state of crisis, his
vigilantism and disregard for authority have put him in danger of
losing his job more than once, and he is a chain-smoker who is
described by Inspector Cobb in Die Hard with a Vengeance as being "two
steps away from becoming a full blown alcoholic", on which McClane
jokingly corrects him saying only "one step". John McClane Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
