Here’s a taste of their exchange:

Sydney, people are already really talking about the physical transformation you make in the movie, the training that you did. What was it about the role that made it seem like you wanted to make that kind of commitment?

Sydney Sweeney: I mean, I couldn’t let Christy down, and I also love transforming for characters. That’s the whole reason of being an actor, is to be something different from yourself and to challenge ourselves.

So I had like two months of training. I built gyms in my house and I had a boxing trainer, I had a weight trainer, I had a nutritionist and would work out and train every single day.

And it was amazing. I loved it. Being able to completely lose yourself for somebody else and then have that person there next to your side. It was transformative.

Katy O’Brian, co-star: It was exhausting watching her do it.

Ben Foster, co-star: And in tribute to Syd, we’d shoot a 12-hour day that was dense, we’ll say, that would be a gentle word. She would then go train and choreograph the fights that she would do back-to-back after, one after another.

Sweeney: I’d be put in the middle of a ring and I’d have like nine girls and they would just drill me with all the different fights, one after the other for like two hours after we would wrap.

Because I really wanted the choreography to match the exact fights that she had in real life. So we would watch all the footage from her fights and memorize all the combinations and then implement those into the fight.

So everything you see were her actual fights. And so I’d wrap, I would do that for two hours, and then I would weight train.

David, there is something very unflinching about the movie. Why was it that you wanted to tell Christy’s story in a way that wasn’t afraid to explore these really dark and disturbing moments in her life?

David Michôd, director: In a way, the dark and disturbing was what made me want to make the movie. I had a clear sense that in this really wild and colorful story of a ’90s boxing pioneer was actually, underneath, it was a very important story to tell about how these coercive control relationships function.

And trying to wrap my brain around what keeps them functioning over, in this case, 20 years. And I knew that where Christy’s story went, it was harrowing.

And what the challenge for me then as a filmmaker was just to go, how do I do this being very conscious of not wanting to step into a world of representations of violence against women and all that kind of stuff, but not shying away from the horror that is very much there and is very palpable.

I could see a big sprawling movie that would start almost as a kind of conventional underdog pioneering sports movie and then morph into something that was deeply moving and important.

Sydney, Ben, what was it like for the two of you performing some of those darker scenes in the film and how did you keep some sense of humanity between the two of you?

Sweeney: There were so many conversations around a lot of those moments, and both Ben and I, we don’t like to rehearse and we kind of just want to feel it. And I think we both became very connected to who we were portraying and —

Foster: Listening.

Sweeney: We just listened

Foster: And Dave created a space where we could do that. And we would block it, we did a lot of talk privately, and then we would come in and jam and nudge. But the truth is Dave is quality control and would fine-tune moments.

The day’s buzziest premieres

‘EPiC: Elvis Presley in Concert’

How deep did Baz Lurhmann go researching his 2022 movie “Elvis”? Forty stories. That’s the depth of the Kansas salt mine where Warner Bros. had stored 59 hours of unseen recordings from Elvis Presley’s seven-year stint in Las Vegas.

Lurhmann studied it for his Oscar-nominated biopic, which mourned Presley as an artist in a cage and wondered who the curious, music-loving boy from Tupelo might have become if Col. Parker had let him, say, visit an ashram with the Beatles.

This time, the “Moulin Rouge!” director has said that he wants to use found footage to “let Elvis sing and tell his story” — as in, Lurhmann’s own spectacular sensibilities will cede center stage to Presley himself, who can still wow a crowd even during a late-career moment when his own fans feared he had more jumpsuits than ambition.

I’ll definitely be at the premiere to pay my respects to the King. — Amy Nicholson

‘Hamnet’

You’re going to be hearing a lot of Oscar buzz in the coming months about various movies, along with people insisting that — seriously — this is the one you need to see. “Hamnet” is, far and away, that film, for three specific reasons.

First, Paul Mescal has now done three masterful turns, between this, “Aftersun” and “All of Us Strangers” confirming what a truly special talent he is. Mescal and the “Hamnet” crew came through our TIFF studio.

Second, I needed director Chloé Zhao to rebound after the mess that was “Eternals” to the confidence she displayed on “Nomadland” — and she’s done exactly that. Read our Telluride interview with her.

Finally, Jessie Buckley has uncorked one of the year’s most impressive turns: a grief-stricken plunge that elevates her to the level of Casey Affleck in “Manchester by the Sea.” Do not be surprised if, like Affleck, she goes all the way. — Joshua Rothkopf
