Half human makes a stronger god

It's all very amusing to see few A list actors humiliating themselves wearing robes, holding spears, spewing thunder and playing gods. Yes, of course they are there getting their paycheck, but still. Danny Huston as Poseidon, Liam Neeson as Zeus, Ralph Fiennes as Hades, Bill Nighy as Hephaestus and Sam Worthington as himself because he can't act.
