Immortals (2011) - IMDb

Here is what IMDB says:
Theseus is a mortal man chosen by Zeus to lead the fight against the ruthless King Hyperion, who is on a rampage across Greece to obtain a weapon that can destroy humanity.

Here is what youtube says:
Let's see how seriously the Americans will fuck up Greek mythology in this movie. - panarkas
