Unlike Aunt Agnes, Ms. Baranski has been known to have nude swimming parties in the moonlight at her lake house in Connecticut with fellow actors like Mark Rylance and Cherry Jones.

“Christine exudes class and grace, but she can throw back a martini eat a hot dog and talk sports with the best of them,” Ms. Margulies said.
