It still seem odd that that Fox has waited so long to make a Percy Jackson sequel, but Sea Of Monsters is now coming together and the latest to sign up, according to THR, is Firefly and Castle star Nathan Fillion.
Fillion will play Hermes, who was the messenger to the Gods in Greek mythology. In Rick Riordan’s Percy Jackson novesl, Hermes is also the father of the antagonist, Luke (Jake Abel). Dylan Neal portrayed Hermes in Percy Jackson & The Olympians: The Lightning Thief, but Fillion will take over here. Logan Lerman, Alexandra Daddario, and Brandon T. Jackson are all returning for this sequel, which sees Percy heading under the waves in search of the fabled Golden Fleece.
Thor Freudenthal is directing Percy Jackson: Sea of Monsters, script by Scott Alexander and Larry Karaszewski. It isn’t known exactly when production will begin on Percy Jackson: Sea of Monsters.
