Clint Eastwood is the name used by Marty McFly in Back to the Future Part III (1990), which parodies a western, though the other characters do not find it intimidating ("What kind of stupid name is that???"). Marty also used a piece of metal as a bulletproof vest in a duel with Buford Tannen (as foreshadowed in Part II when Biff is watching A Fistful of Dollars in his hot tub). When McFly returns to the future, it is thought that he died in the process, and as such a ravine is named "Eastwood Ravine" after him.
