In a CBS Sunday Morning interview, the main quartet of Being the Ricardos sat down with Mo Rocca to discuss all things I Love Lucy, the show at the center of Aaron Sorkin’s upcoming film. Watch Nicole Kidman, Javier Bardem, Nina Arianda, and J.K. Simmons above.

In the interview, the performers talk about doing their characters—both the actors and their on-screen personas—justice. Kidman plays Lucille Ball/Lucy with Bardem as Desi Arnaz/Ricky, Arianada as Vivan Vance/Ethel, and J.K. Simmons as William Frawley/Fred. The film follows the production of an episode from its table read on Monday to a live taping on Friday, all while Lucy and Desi face three media nightmares that threaten to upend their successful TV show—and their marriage.
