The actress portrays the 'I Love Lucy' star in the upcoming film 'Being the Ricardos'.
Nicole Kidman is opening up about how she felt stepping into Lucille Ball's shoes.
In a recent conversation with Chris Rock for Variety's Actors on Actors series, the Oscar winner discussed playing the comedy legend in Aaron Sorkin's upcoming movie, Being the Ricardos.
About perfecting Ball's voice, Kidman said she "had to put in an enormous amount of time on Lucille Ball right now, because she has a very particular way of speaking."
Agreeing with with Rock's comment that Ball was "just one of the most talented people to ever roam the earth", the Undoing star told the 56-year-old comedian, "I am way out of my comfort zone right now, Chris! I'm free-falling."
"I'd like to be funny. I'm never cast funny", she added.
Being the Ricardos is a biographical drama set during a week of production of I Love Lucy. The film will focus on Ball and her husband Desi Arnaz (played by Javier Bardem), who famously starred together in the iconic sitcom from 1951 through 1957.
Ball and Arnaz's tumultous marriage lasted for 20 years, from 1940 to 1960.
