Jon Favreau "reached out" to Beyoncé to secure her role as Nala in the new live-action remake of The Lion King.
The filmmaker was thrilled when the singer agreed to voice the part of Nala.
Speaking at the European premiere of The Lion King, held in London's Leicester Square, he said: "I reached out to her. I thought she'd be wonderful for Nala and when you see what she's able to do with the role and the songs, it's quite wonderful."
And Favreau is full of praise for the cast and how they "improvised" to make the movie seem more like a "standard theatrical dramatic performance".
He added: "I wanted to create something that felt live action, even though every environment is digitally generated, every performance is hand animated. We wanted it to feel like a live action film almost like a documentary and part of what contributed to that was to allow the actors to overlap and improvise. We put them together in almost what looks like a theatrical rehearsal in a black box theatre.
