On the carpet, Rachel commented on the weight Colin had to gain for the role.

“I’d never met Colin before. I met him when he had the increased weight and his face and his jawline were like doughy flesh, so he will always be [his character] David to me,” she explained.

Colin added that he tried to convince director Yorgos Lanthimos to change his character’s appearance.

“I didn’t want to put on weight because I didn’t want to work to lose it, so I was saying to Yorgos, ‘What about if he’s really thin?’ Because I did want to alter my physicality somewhat.”

Looks like Colin lost that battle but is back to looking better than ever!

FYI: Rachel is wearing an Alexander McQueen gown. Colin is wearing head-to-toe Dolce&Gabbana.
