“CBS Sunday Morning” spotlights 70th anniversary of “I Love Lucy” and cast of “Being the Ricardos”

The sitcom I Love Lucy, starring Lucille Ball and Desi Arnaz, was a ratings powerhouse in the 1950s, and a perpetual hit in reruns ever since. To mark the series’ 70th anniversary, CBS Sunday Morning correspondent Jim Axelrod looks back at the making of a TV classic. He talks with granddaughter Kate Luckinbill, head of creative direction at the production company Desilu; visits the Lucy-Desi Museum and the National Comedy Center, both in Ball’s hometown of Jamestown, N.Y.; and sits down with Darin Strauss, author of “The Queen of Tuesday,” a novel inspired by Ball.

Starring as Lucille Ball and Desi Arnaz in Being the Ricardos, Nicole Kidman and Javier Bardem felt intense pressure playing two of the most famous people in television history. Correspondent Mo Rocca talks with Kidman and Bardem, and with co-stars J.K. Simmons and Nina Arianda, about the challenges of recreating the cast of “I Love Lucy” in Aaron Sorkin’s latest film, which goes behind the scenes of a trailblazing career couple.
