Nice words from casting director Cassandra Kulukundis about Leo: What are some of the qualities that make Leo perfect as Bob? I’ve never seen anyone, especially at that level, come in every single day with ideas to create an unbelievable character in Bob from the ground up like Leo did. Bob is intelligent, a bomb expert, a stoner, and he’s funny and heartfelt. Over the years, he’s gotten soft but has raised Willa to be strong and independent. Leo’s not a father in real life, but he’s so paternal in this film. When Bob talks with Sensei (Benicio Del Toro) about not being able to do Willa’s hair, Sensei says, “Don’t go dark on me, Bob.” He makes me want to cry every single time I see that. I feel so bad for Bob, he didn’t even take off his bathrobe the entire time. He’s not going to stop until he finds his daughter. There’s so much nuance to it. I think it’s an incredible performance, truly his best work. The Revenant and this are, to me, some of the best films. He was more than an actor-for-hire; he was a collaborator with Paul on every level. It’s like watching an incredible tennis match. I got a whole new respect and understanding of what Leo does from this film. Motion Picture AssociationFour Acting Nominations. One Casting Director.
