One of the film's biggest transformations goes to Jared Leto as Paolo Gucci — and, if you've seen the actor in Dallas Buyer's Club or Little Things, you know he's not afraid to fully commit to a look — which was indisputably the character that spent the longest in the makeup chair.
"Between everything, from the costume to the prosthetics to the makeup, it would take anywhere from three to five hours, depending on the day," said Carboni. "We realised he would need a lot of prosthetics work for Jared early on, so decided to bring in [prosthetics designer] Göran Lundström who was just dedicated to him. He worked endless hours with his team to make him look as similar to the real Paolo, who was older and more round. He designed all the things — a bald cap, prosthetics to create a thicker nose, cheeks, even his neck — so it's full-on prosthetic, but the amazing thing is you really couldn't tell. It looked very realistic."
