This is Renee Zellweger:
And this is Judy Garland, circa 1960:
According to Variety, the film will focus on Garland's arrival in London in the late '60s for a series of sell-out concerts, shortly before her death. It will explore "the unfolding family drama" she was dealing with at the time, as well as her relationships with her fans and fellow musicians.
Michael Gambon, Finn Wittrock and Jessie Buckley star alongside Zellweger.
