Renee Zellweger will play Hollywood icon Judy Garland in her next film project, which focuses on Garland at the latter stages of her tragically short life.
The Bridget Jones star will play the ill-fated Wizard of Oz actress and singer in Judy, which will centre on her final concerts in London in the late 1960s.
Britain's Rupert Goold will direct the biopic, which is set to begin filming in February 2018.
The 48-year-old Zellweger is currently one year older than Garland was when she died of an drug overdose in June 1969.
Judy is written by Tom Edge, whose CV includes Netflix's royal drama The Crown and the BBC's adaptations of JK Rowling's pseudonymously-written Cormoran Strike novels.
The film will open in the winter of 1968, when Garland came to London to perform a series of sell-out concerts at the then prestigious Talk of the Town venue, which is now the Hippodrome Casino.
Best known for playing the title role in the three Bridget Jones films, Zellweger has also starred in films as diverse as Chicago, Jerry Maguire and Cold Mountain. For her performance in the latter she won Oscar, BAFTA, Golden Globe, and Screen Actors Guild awards.
