Eventually, though, the principal roles went to Gaga and Bradley, with the latter on double duty as both actor and director.
However, at the Santa Barbara International Film Festival last week, he revealed (as reported by IndieWire) that things could have ended up looking quite different.
“I thought about Adele for a while,” he admitted, before revealing this version of the plot would have seen his character struggling with his career and heading abroad where he’d meet a woman portrayed by the Someone Like You singer who would change his life.
“That never even took off at all,” the Maestro star added.
A Star Is Born finally hit cinemas in 2018, marking Gaga’s first time as the lead in a film.
It was nominated for eight Oscars, including acting nods for Bradley, Gaga and their co-star Sam Elliott, and was awarded Best Original Song for the singer’s chart-topping contribution to its soundtrack, Shallow.
