According to the trailer — and title — for "Muhammad Ali's Greatest Fight," the "Rumble in the Jungle" was nothing compared to Ali's battle to avoid going off to war.

The pugilist and pacifist cited the Holy Koran as his reason to refuse to fight in Vietnam. Not everybody agreed with his point of view, and a divided nation reacted passionately as either side.
