On the "90210" spinoff, Dustin Milligan, who appeared last summer in the short-lived CW drama "Runaway," has been cast in the supporting role of Ethan. Character is a likable jock who falls out of favor with the in crowd and starts hanging out with the "90210" crew.

Then there's Noble, who will play Trish Wellington on the murder mystery "Harper's Island."

Noble, the daughter of "Lord of the Rings" thesp John Noble, managed to book the "Harper's" gig just hours after touching down at LAX.

Noble, who began in modeling, starred in the Australian oater "Gabriel."

CBS Paramount Network TV is behind the project. Also newly cast on the project: Ryan Merriman ("Smallville") and Elaine Cassidy ("The Lost World").

Jon Turteltaub is helming "Harper's Island," as well as exec producing.
