'Baywatch' Reboot Casts Thaddeus LaGrone and Hassie Harrison

Fox's Baywatch reboot has added Hassie Harrison and Thaddeus LaGrone to its lifeguard roster, joining Stephen Amell, Jessica Belkin and a returning legacy cast member. The series blends familiar characters with a new generation, reviving the show's slow-motion beach runs and high-stakes water rescues for a modern audience.

Harrison will play Nat, described as "a former foster kid turned Olympic athlete. Nat is the gold standard when it comes to lifeguarding. Brilliant, driven, and fiercely loyal, she's Hobie's right hand and closest friend." She previously played Laramie for three seasons on Yellowstone and has credits in Tacoma FD and the 2025 survival horror film Dangerous Animals, with upcoming roles in The Rescue and Deep Eddy.

LaGrone takes on the role of Brad, characterized as someone who "served two tours in an elite division of the Marines before returning back home to Venice Beach to care for his ailing father.
