Renée Zellweger hasn't had a major acting role in three years, however the Oscar-winner has shown that she's still got it in the trailer for her new movie, Judy.
Zellweger, 50, plays actress Judy Garland in the final year of her life before a drug overdose killed her at age 47, reports news.com.au.
It is Zellweger's first role since she headlined the 2016 film Bridget Jones's Baby.
She told People magazine that she spent two hours a day in hair and make-up to turn into the former child star.
"It was such a joy learning about the magnificence of this person," she said of preparing for the part. "I always admired her. She was so quick and so funny. She could hit the ball back with the best of them."
Zellweger also took singing lessons and studied Garland's moves to transform into the star, reports news.com.au.
She co-stars with American Horror Story's Finn Wittrock as Mickey Deans (Garland's fifth husband) as well as Michael Gambon in the role of her manager, Bernard Delfton.
Rufus Sewell plays her third husband, Sid Luft, with whom Garland had a daughter, Lorna (Game of Thrones' Bella Ramsey), while Gemma-Leah Devereux plays a young Liza Minnelli, Garland's daughter with director Vincente Minnelli.
Zellweger is the latest actor to play Garland with many trying their hand at impersonating the singer over the years.
Chrissy Amphlett gave a brilliant performance as Garland in The Boy from Oz musical, while Judy Davis won an Emmy for her take in Life with Judy Garland: Me and My Shadows.
The movie is set to hit cinemas in September.
The long-time couple shocked fans when they announced their split this week.
