Lucie Arnaz and her brother Desi Arnaz Jr. are executive producing their parents' official biopic.

The Being the Ricardos movie will follow Lucille and Desi during a rollercoaster week of filming the 1950s television series I Love Lucy. The storyline begins during a Monday table read and wraps up with a TV shoot on Friday in front of a live audience, Deadline previously reported.

Speaking to the magazine, Lucie revealed news details about the film, sharing, "It takes place, primarily, during rehearsals for one of the shows. There are a few scenes where they're at their house in Chatsworth, before working, after working."

"There are two or three short flashback scenes to her life before I Love Lucy, when she worked on the radio show, when she was trying to convince the network to hire dad," Lucie continued, before noting Aaron has taken some creative liberties with the script. "But stuff happens that week that didn't happen altogether the way Aaron has written it. He's taking some theatrical license and sort of cramming a couple of true events that did happen, they just didn't happen at the same time."
