Jon M Chu encouraged fans to take their audio experience into their own hands, ahead of the film’s opening weekend

Wicked director Jon M Chu is encouraging audience members to ask their cinema to turn up the volume on his blockbuster musical, as some viewers have begun reporting sound issues.

Posting on X on the evening of Wicked’s US opening, Chu wrote: “Tell your movie theater to turn it up to a 7 … I’ve gone to a couple screenings and they are more like a 6.4. If you want it the way it was intended 7 is the way.”
