The first book in the "Percy" series, "Percy Jackson & The Olympians: The Lightning Thief," was released in 2010 and starred "The Perks of Being a Wallflower" actor Logan Lerman as Percy, "Tropic Thunder" actor Brandon T. Jackson as Grover, "Parenthood" actress Alexandra Daddario as Annabeth. Other stars included Sean Bean of "Game of Thrones" as Zeus and "Grey's Anatomy" actor Kevin McKidd as Poseidon. The movie received middling reviews and currently holds only a score of 47 out of 100 on review aggregator Metacritic. But the movie did big business at the box office all around the globe, regardless.
