We may not have loved Percy Jackson: Sea of Monsters, but director Thor Freudenthal's comics about the making of the film are perfectly delightful. He reveals what it was like to film the movie's effects-driven scenes and what Nathan Fillion was like on-set.
The first Percy Jackson movie was pretty much a straight-up copy of Joseph Campbell's Hero's Journey, in which a hero finds out he's chosen and goes on a series of tests. And now the new outing basically does the same thing all over again, except slower and with less alacrity. Call it the monomyth with mononucleosis.
