A colorful action film about the Battle Of Thermopylae in 480 B.C. in which the Spartans defend themselves for a Persian invasion against overwhelming odds. King Leodinas (Richard Egan) rallies the locals to stop the attack of thousands of plundering Persian invaders led by evil King Xerxes (David Farrar). Sir Ralph Richardson as Themistocles of Athens leads the international cast this the spectacular cinematic conflict that has more emphasis on action rather than historical accuracy. ~ Dan Pavlides, All Movie Guide
