TV Guide has confirmed that Alan Ritchson (Titans, Supergirl) has been cast as the titular character in the upcoming TV adaptation of Lee Child's bestselling novel series.The streamer announced it was developing this new series back in July of 2019 (no doubt after seeing such success with Jack Ryan), and then six months later picked it up to series.
