James Gunn has promised Lex Luthor will be an "imposing" villain in 'Superman'.
The 58-year-old director has promised his upcoming superhero blockbuster - which will feature David Corenswet in the title role opposite Nicholas Hoult as his arch-nemesis - will be different to previous tales about the comic book hero as he's developed a villain who is genuinely scary and will leave fans fearing for Superman's fate.
