Hester

Veteran British actress Lumley has joined the cast as Hester Frump, Wednesday's grandmother and closest ally.

"The first day on set when Joanna walked on, she just was Hester and she nailed every single line, and it's just so delicious," said show creator Miles Millar.

Hester is a friendless, Type-A workaholic whose work includes helping corporations sidestep the EPA.

When her Whitman-quoting oncologist breaks the bad news, Hester remembers her mother’s early death from cancer.

Hester figures she’ll say goodbye to all that with drop-ins on a college ex in Pittsburgh, and another on an old high school friend in Chicago.
