After playing Ryan Reynolds' younger self in Netflix's The Adam Project, Walker Scobell has now been cast as Percy Jackson in the Disney+ adaptation of the book series.

In the post, Riordan included screenshots of the January 28 Zoom call, where Schobell learned about his casting for the first time.

Riordan said in a statement:

"It was obvious to me and the rest of the team that Walker had the perfect mix of comedic timing, sweetness, rebelliousness, snark and heroism to embody our hero Percy Jackson."

Percy Jackson's age in the books compared to Walker Scobell's age

Logan Lerman was around 18 in 2010 when the first Percy Jackson film came out. However, the live-action take on the character was aged up significantly compared to the original books.

With Walker Scobell's casting, it seems that the series is going with a more accurate representation of the young demigod.

In the first novel of the series, The Lightning Thief, Jackson is only 12 years old. It has been established that the titular character's birthday is on August 18. This means that Scobell is only a year and eight months older than the Olympian demigod he would be portraying in the Disney+ series.
