What Ever Happened to the Cast of Newhart?

After Newhart ended, Frann remained a familiar face on television, appearing in Diagnosis: Murder, Lois & Clark: The New Adventures of Superman, and several made-for-TV movies. She also devoted time to charity work, especially causes supporting children and women’s shelters, earning respect for her generosity offscreen.

Mary Frann passed away unexpectedly in 1998 at age 55 from heart failure. Her death shocked fans and colleagues, who remembered her as elegant, kind, and endlessly professional. To this day, she’s cherished as Joanna Loudon — the woman who made the Vermont inn feel like home.
