'Superman' stars David Corenswet and Nicholas Hoult had some sweet exchanges with Henry Cavill, Tyler Hoechlin, and Michael Rosenbaum

As for Hoult, he connected with Smallville's Michael Rosenbaum. "Honestly, he was so kind and encouraging, and he really gave me a freedom and a confidence and a support that felt really lovely going into it," the actor explained. "He was probably the first person I saw play Luthor when I was growing up. So to get to interact with him and to chat with him beforehand was really special. I appreciate that from him, his time, but also just his encouragement meant a lot."

He then shared, "The beautiful thing he said was, 'You've got this. Go have fun. It's a, weirdly, kind of uplifting and wonderful thing to play a character that you've watched someone play and do a brilliant job at, to then have them say, 'Yeah, go get it. Go take it on.' That's a really bolstering sort of thing to happen. It was very kind of him to do that because I suppose it's a weird thing taking on a character that other people have played in some ways. Normally in acting, there's no comparisons, really, when it's a unique character, but when there's been different interpretations, then obviously people do compare."

The rest of the cast includes Rachel Brosnahan, Anthony Carrigan, Skyler Gisondo, Sara Sampaio, Mariìa Gabriela de Fariìa, Wendell Pierce, Pruitt Taylor Vince, Neva Howell, Alan Tudyk, Nathan Fillion, Edi Gathegi, and Isabela Merced.

James Gunn's Superman, DC Studios' first feature film, will be released in theaters on July 11.
