As of October 2023, there is no official announcement regarding a third movie in the "Percy Jackson" film series following "Percy Jackson: Sea of Monsters." However, a new live-action series titled "Percy Jackson and the Olympians" is in development for Disney+, set to premiere in December 2023. This series aims to closely adapt Rick Riordan's original book series, which may lead to further adaptations of the subsequent books if successful.

No, "Percy Jackson: Sea of Monsters" is not the last movie in the Percy Jackson film series. It is the second film, released in 2013, following "Percy Jackson & the Olympians: The Lightning Thief" (2010). Although a third film was planned, it was never produced. The series was ultimately not continued in film format. However, a new adaptation of the Percy Jackson books in the form of a Disney+ series is currently in development, which aims to provide a more faithful representation of the source material.

Yes, "Percy Jackson: Sea of Monsters" is a movie released in 2013. It is the sequel to "Percy Jackson & the Olympians: The Lightning Thief" (2010) and is based on the second book in Rick Riordan's "Percy Jackson & the Olympians" series. The film follows Percy Jackson and his friends as they embark on a quest to find the mythical Golden Fleece to save their home, Camp Half-Blood, from impending doom. The film features a mix of adventure and fantasy elements, appealing to fans of the book series.

As of my last knowledge update in October 2023, there is no official release date for Season 2 of the "Percy Jackson" series. The series is based on Rick Riordan's "Percy Jackson & The Olympians" books and is separate from the "Percy Jackson: Sea of Monsters" movie. The first season was announced to be in production, but specific details about the second season, including its release date, have not been provided.
