Cate Blanchett to play US TV legend Lucille Ball in biopic written by Aaron Sorkin

Ball's children Lucie Arnaz and Desi Arnaz Jr will serve as producers on the film

Cate Blanchett is attached to star in an authorised biopic of legendary American TV star Lucille Ball.

The film’s script is being written by The West Wing‘s Aaron Sorkin, and is said to concentrate on Ball’s marriage to Desi Arnaz, with whom she starred on classic 1950s sitcom I Love Lucy. The couple’s children, Lucie Arnaz and Desi Arnaz Jr, will serve as producers on the film, TheWrap reports, though its director has yet to be announced.

Ball and Arnaz were married from 1940 to 1960 and co-created I Love Lucy, which ran from 1951 to 1957, becoming one of the most popular TV sitcoms of the era. The couple also founded their own TV studio, Desilu, which made shows including Star Trek and Mission: Impossible.

After buying out Arnaz in 1962, Ball ran Desilu single-handed until 1967, becoming the first woman to head up a major TV studio. She then sold Desilu to Gulf + Western, who renamed it Paramount Television. Her other popular shows included The Lucy Show, which ran from 1962 to 1968, and Here’s Lucy, which ran from 1968 to 1974 and co-starred her two children.

Ball died in 1989 at the age of 77, having been married to second husband, stand-up comedian Gary Morton, since 1961.
