Renée Zellweger Stars as Judy Garland in Her Final Days in 'Judy' Trailer

Jessie Buckley, Finn Wittrock, Rufus Sewell and Michael Gambon round out the cast of the Rupert Goold-directed film.

The first full-length trailer for the Judy Garland biopic Judy dropped Monday.

Beginning in the winter of 1968, the film follows Garland (Renée Zellweger) as she performs a five-week run of her sold-out concert at The Talk of the Town nightclub in London. The biopic picks up with the actress and singer 30 years after her career-defining role in The Wizard of Oz as she battles with her management, charms fellow musicians and reminisces with friends and adoring fans about her career. Judy was adapted from Peter Quilter's musical End of the Rainbow and explores Garland's final days before she died of an accidental overdose at the age of 47 in June 1969.

Jessie Buckley, Finn Wittrock, Rufus Sewell and Michael Gambon round out the cast of the Rupert Goold-directed film.

The trailer opens with Judy checking into a hotel. After the employee calls her "Miss Garland," she corrects him and tells him to call her by her first name. He soon informs her that her suite is not available because she owes money to the hotel.

After she is turned away from the hotel, Judy and her young children look for a place to sleep. As Judy takes pills, her daughter asks that she doesn't fall asleep. "These are the other ones," she responds.

In addition to her struggles to balance motherhood with her career, Judy also finds herself at a professional crossroads in the trailer when she admits that she can't get a manager.

She accepts an opportunity to perform at Talk of the Town. "You're saying I have to leave my children if I want to make enough money to be with my children?" she asks before agreeing to the concerts.

As Judy embarks on the five-week run of sold-out concerts, she becomes closer with her eventual fifth and final husband, Mickey Deans (Wittrock).

The icon's health begins to deteriorate as the trailer continues. Judy performs a rendition of "Somewhere Over the Rainbow" as her peers tell her to take better care of herself.

"Everybody has their trouble," she says in a voiceover as clips show her performing onstage and interacting with her children. "And I've had mine. I just want what everybody wants. I just seem to have a harder time getting it."

The trailer concludes with Judy performing for a sold-out crowd. "You won't forget me, will you?" she asks as the crowd applauds. "Promise you won't."

A teaser trailer for the film was released in May. The minute-long clip previewed Garland arriving in London for the concerts as a stripped-down version of "Somewhere Over the Rainbow" played.

Judy will be in theaters Sept. 27. Watch the full trailer above.
