The actor, who plays Peter Sutherland in The Night Agent, has signed on as a series regular on the show, which stars and is executive produced by Emmy winner Julia Garner. His casting comes on the heels of The Night Agent wrapping production on its fourth and final season.
Basso joins previously announced series regulars Lewis Pullman, known for Thunderbolts and Top Gun: Maverick, and Maddie Hasson. Mary-Louise Parker is also set to return. Character details for Basso's role have not yet been revealed.

Guilty Creatures comes from director Craig Gillespie, who made I, Tonya and Cruella, and showrunner Stuart Zicherman, with Tomorrow Studios producing. The series is adapted by Sarah DeLappe from Mikita Brottman's true-crime book Guilty Creatures: Sex, God, and Murder in Tallahassee, Florida.
According to the official synopsis, the drama is "set against a backdrop of sex and murder in the Florida Panhandle" and "delves into the psyche of a torrid romance and subsequent act of murder between two young, adulterous but God-fearing lovers", believed to be played by Garner and Pullman, "unravelling their complex lives and the emotional toll of living as killers for 18 years".
