I always thought of her as a sit-com star.
I doubt they were the toasts of Broadway then.
On stage, she won the Tony Award for Best Actress in a Play playing a strong-willed mother in the Neil Simon play Broadway Bound (1987). She was Tony-nominated for her roles in Last of the Red Hot Lovers (1970), The Diary of Anne Frank (1998), The Tale of the Allergist's Wife (2001), Collected Stories (2010), and The Lyons (2012). She is also known for acting in It's a Bird... It's a Plane... It's Superman (1966), On a Clear Day You Can See Forever (1967), Gypsy (1990), The Sisters Rosensweig (1993), and Follies (2011). She made her film debut in Damn Yankees! (1967) and later had roles in The Morning After (1974), The Muppets Take Manhattan (1984), I Want to Go Home (1989) and Being the Ricardos (2021).
So not the biggest Broadway star but she did okay after her TV years.
