Fans of "Percy Jackson and the Olympians" will have to wait a little longer as the beloved series may not hit the screens until 2024.

The upcoming Disney+ show, which is based on executive producer Rick Riordan's best-selling book series, was originally expected to release in 2023.

"We are on track with our schedule, and everything is going according to plan, though we still have a long way to go before this series is ready," Riordan said in a blog post.

"We have sort of mostly finished the principal photography for season one/episode one and have done a good chunk of the filming for episode 2 [but] principal photography just gives us the raw puzzle pieces which will then need to be put together with a soundtrack, special effects and editing to yield a finished product. And we still have a lot of filming yet to do to get all those puzzle pieces for the whole season," he added.

The upcoming series follows the story of Percy Jackson (played by Walker Scobell), a 12-year-old descendant of a Greek god who has recently discovered his divine powers and is accused of stealing the sky god Zeus' lightning bolt. Percy enlists the help of his friends Grover and Annabeth (played by Aryan Simhadri and Leah Sava Jeffries) to search for the lightning bolt in order to save Olympus, the place where the gods live.

As a newbie in TV production, Riordan said he now has a better understanding of the processes involved in making a series. Though the filming of Season 1 episodes might wrap up by next year, the post-production will take "months and months" more, he explained.

"It's probably going to take us through December or into January to film all the episodes of season one, which is roughly one month of filming per episode (eight episodes total)," he revealed. "That means post-production will begin in early 2023 when the pieces are fitted together…This process also takes months and months, and that's not even accounting for closed-captioning, subtitling and dubbing into other languages for our international viewers."

Riordan promised viewers that the series is worth the wait as he himself waited for over 15 years for its "proper adaptation" on the small screen.
