Well, years ago, Madeleine Olnek and I met at NYU Drama School. A very important incident took place with her, didn't it? Tell the story of connecting with Madeleine Olnek. My guest Molly Shannon, since she was last here, has gone on to be in 'The White Lotus” on HBO and her most recent show is now on Showtime 'I Love That for You.' She also has a new memoir, 'Hello, Molly!' I don't know how you culled the stories that you use because they all basically build this mosaic of Molly Shannon.

The following interview has been abbreviated and edited for clarity. And she says her father was her biggest cheerleader and her first acting teacher. She talks about the genesis of her SNL Catholic school girl character Mary Katherine Gallagher. This week on The Treatment, Elvis welcomes back actress Molly Shannon, who is currently starring in the Showtime series “I Love That for You” and has written a memoir “Hello, Molly!” Shannon, a “Saturday Night Live” alum, has also recently appeared in the HBO series “The White Lotus” and “The Other Two.” Shannon, who lost her mother and sister in a car accident as a young girl, tells The Treatment she began her memoir with the accident because it deeply impacted the direction of her life.
