90210 Scoop: Jessica Walter to Play the Drunk Granny!

It isn't Kelly Bishop, but this will do rather nicely: Sources confirm to me exclusively that
Arrested Development's grande dame,
Jessica Walter, has been cast as hard-drinkin', faded, '70s-movie-star Tabitha Mills on the CW's fast-tracked-for-fall
90210 update.
To recap: Tabitha is the grandmother of the show's central teens, siblings
Brenda Annie (Shenae Grimes) and
Brandon Walsh Dixon Mills. As I
reported yesterday, Lori Loughlin will play the pair's mother. The role of the dad (and Tabitha's son) has yet to be cast.
I don't know about you, by my excitement about this show just swelled tenfold.
This Just In:
Dirt's
Ryan Eggold has snagged the role of Ryan "the teacher."
