Corenswet's physical trainer breaks down the routine that helped the formerly svelte actor put on 40 pounds of muscle—and how he got Nicholas Hoult prepped for Lex Luthor.

Clark Kent may call Delaware home in the new movie, but the Philly-born lead actor gets to show home hometown love too.

Since March 2023, Corenswet has been married to actor Julia Best Warner, whom he met at an acting summer camp when he was still a young boy. Though their wedding was years ago, the pair only made their red-carpet debut this week, at the Los Angeles premiere of Superman. Warner and Corenswet also have a one-year-old son.
