How about you, Benicio. What was his pitch like to you?

Del Toro: 'It's happening baby!' (laughs). He just said, he had this movie. Leo was already in it. I think I might have been the second one onboard. I didn't even ask for the script. I said, 'Sure.' That's what happens when you have a filmmaker like Paul Thomas Anderson. We're both cinephiles. We love movies. We want to be in good movies. So, when a filmmaker like Paul reaches out to you, it's a gift. I can't answer it any other way. It's a no-brainer to say yes, then you deal with the part and the script.

If there's one theme that you hope resonates after audiences watch One Battle After Another, what would it be?

DiCaprio:The premise of this was based on the Weathermen of the late 1960s; people who were speaking out; people who were speaking out on civil rights, Vietnam, imperialism, capitalism. So, what if that was put into a modern context? How in the day and age that we're in, how do we communicate any more? There's so much disagreement, and Paul's just holding a mirror up to society ... But at the heart of this movie, you have characters that have a humanity to them. They're just trying to do the right thing. They're just trying to reconnect with their family and create family. He's able to tackle these complex issues, but it's the humanity in these characters. They feel like real people and it's very relatable to mass audiences. I just hope that people will go out and see it because it's a truly original concept by a filmmaker that's trying to do something different.
