Movie fans are being warned they must not sing along to music in the new Wicked film.
The movie, which features British singer and actress Cynthia Erivo and American star Ariana Grande, will be released in UK cinemas on Friday 22 November.
However, according to an advisory video shown moments before the film in the US, AMC Theatres tells the audience “silence is golden” and fans should stay quiet so everyone can “enjoy the magic of movies”.
It urges people not to talk or text, adding “no singing, no wailing, no flirting, and absolutely no name calling”.
Ryan Noonan, an AMC spokesman, told IndyStar: “The Wicked pre-show spot incorporates the themes of the film as a fun, engaging reminder to moviegoers to not disrupt the experience for those around them as they enjoy the show.”
Some fans have posted on social media saying they may find it difficult to resist joining in with the songs in the film, which is an interpretation of the hit Broadway and West End musical.
Part one of Wicked will be released on Friday, followed by part two in November 2025.
The movies explore the friendship between Elphaba, played by Erivo, and Glinda, portrayed by Grande, before they become estranged.
The characters come from the classic Oz stories by American author L Frank Baum – a series which also includes The Wonderful Wizard Of Oz.
In Baum’s works, Elphaba is known as the Wicked Witch Of The West and Glinda as the Good Witch Of The South.

Earlier this week, the stars of the movie attended the London premiere at the Royal Festival Hall, Southbank Centre.
Jon M Chu, the film’s director, channelled the Emerald City of Oz in a forest green velvet suit jacket with a black bow tie and trousers, finishing the look with a pair of silver infinity glasses.
Erivo and Grande took inspiration from the original musical production, opting for black and yellow outfits respectively.
