Dustin Milligan (The Messengers) is the first actor to join the cast of the CW’s planned spinoff of Beverly Hills 90210 from executive producer Rob Thomas (Veronica Mars). According to the show’s producers, Milligan, who also appeared in the short-lived CW show Runaway, will play a “likable, genuine…star athlete” named Ethan who befriends the 90210 group of teens.

Published reports have said the spinoff will revolve around the Mills family of Beverly Hills whose matriarch, Tabitha, is a 60-something has-been actress and alcoholic. Tabitha’s adult son, Harry, moves back to Beverly Hills to care for his mother. Joining him are his wife Celia, an Olympic athlete-turned-personal trainer, and their two 16-year-old children who may make up the new 90210 crew.
