It's always a B-film bonanza when Greek myth meets Hollywood high-tech. 'Twas ever thus, since Jason and his Argonauts sailed Ray Harryhausen's wine-dark seas through the kraken's release in Clash of the Titans.
Do not the gods deserve the best special effects we can lavish upon them? By Hera's hairy lip, they do!
They also probably deserve a cohesive plot and dialogue that clarifies rather than confuses, but in The Legend of Hercules, they'll have to settle just for the special effects.
Here's the CliffsNotes version (which they really should pass out as you enter the theater): It's 1200 B.C. and Hercules (Kellan Lutz, who looks like the late Paul Walker on industrial-strength steroids) is banished to Egypt by evil King Amphitryon (Scott Adkins). There he is taken captive and must fight as a gladiator in order to make his way back to Greece before his beloved (Gaia Weiss) is forced to marry another man.
