Even though Arrested Development is still not officially, totally, completely dead in the water, its pulse continues to weaken. According to the Hollywood Reporter, Bluth-family patriarch Jeffrey Tambor has been cast opposite John Lithgow in NBC's Twenty Good Years pilot, about two fiftysomethings who decide to live it up while they still can. Is it too much to hope for at least a cameo by Jessica Walter? God help me, I miss her already.
