Aaron Sorkin is in talks to write the script, which will center on Ball's 20-year marriage to Desi Arnaz. She eloped with the Cuban bandleader in 1940, and the two created the massively successful sitcom "I Love Lucy" in 1951 through their Desilu Productions. She won four Emmys for the role.

Ball also gave birth to her daughter in 1951 and to her son in 1953. Ball and Arnaz divorced in 1960, and Ball began running Desilu Productions in 1962. She died in 1989.

Jenna Block will oversee development of the project at Sony-based Escape Artists. No director or other cast is attached yet.
