Scream Queens” adds a former teen heartthrob, “Shooter” sets its sights on Omar Epps and a “Seinfeld” alum gets ready for “The Grinder” in this casting roundup …

Former “One Tree Hill” star Chad Michael Murray has joined buzzy Fox series “Scream Queens” as Brad Radwell. The character’s parents were apparently avid readers of “The Official Preppy Handbook,” as Entertainment Weekly reports that he is the older brother of “Queens” characters Chad (Glen Powell) and Thad (Patrick Schwarzenegger). Mom and dad will be played by Alan Thicke and Julia Duffy, according to E! News.

USA’s “Shooter” pilot has cast “House” and “Resurrection” alum Omar Epps as Secret Service agent Isaac Johnson, the former commanding officer of Ryan Phillippe’s Bob Lee Swagger, according to TV Line.

Jason Alexander will guest star on Fox’s new comedy “The Grinder” as Cliff Bemis, the gruff, bull-headed creator of “The Grinder,” aka the TV series that made Rob Lowe’s Dean Sanderson a household name.
