The surfing scene in Apocalypse Now (1979)
Considering the milieu—beach combat in Vietnam—Robert Duvall's Lieutenant Colonel Kilgore is arguably the most dedicated sportsman ever to grace the silver screen. Charlie might not surf, but Kilgore's men do, enemy fire be damned. ("If I say it's safe to surf this beach, Captain, it's safe to surf this beach.")

Elyse fails—but the nuptials are on when Eddie allows that she probably would have correctly answered the " Alan Ameche question," had not pal Shrevie (Daniel Stern) blurted out the answer first.
