Beverly Hills 90210 Spinoff

Two more have moved into 90210.

Ryan Eggold and Jessica Walter have joined the cast of the CW's Beverly Hills, 90210 spinoff, which centers on the Mills, a three-generational Beverly Hills family whose two teen kids are attending West Beverly High.

Walter will play Tabitha Mills, the former Hollywood star grandmother whose alcohol problem triggers her son and his family's move from Kansas to Beverly Hills.

Eggold will play Ryan Matthews, a cool English lit teacher at West Beverly High whose unorthodox teaching style puts him at odds with his fellow teachers and sometimes too close with his students.

In the pilot, to be directed by Mark Piznarski, Eggold and Walter are joining previously cast Shenae Grimes, Lori Loughlin, Annalynne McCord and Dustin Milligan.

Eggold most recently co-starred on FX's Dirt and is in CBS' pilot Mythological Ex. He is repped by TalentWorks and Generate.

Veteran actress Walter also played the grandmother on Fox's acclaimed comedy Arrested Development, for which she earned an Emmy nomination.
