“First Blood” (1982)

While David Morell's original book and the first film adaptation were more about the struggles of former Army Green Beret John Rambo (Sylvester Stallone) after he returned from Vietnam, it was the character's astonishing fighting chops — memorably intoned by his former commander (Richard Crenna) — that audiences enjoyed. In three sequels, Rambo went back into battle against the communists in Vietnam, Russian troops in Afghanistan and rebels in Burma.
