Superman Trailer Easter Egg Reignites Speculation About Robert Pattinson's Batman Joining The DCU - But There's One Key Problem

One subtle detail in the new Superman trailer could be read as a hint that Matt Reeves' The Batman franchise actually takes place in James Gunn's DCU. The new Superman trailer offers a better look at several characters like Metamorpho, the Engineer, Guy Gardner, and Ultraman, as well as a glimpse of Clark Kent and Lois Lane's romantic relationship. It's now clear that David Corenswet's Superman will redefine the concept of superhero in the DC Universe, and he will receive pushback from villains like Lex Luthor and other members of the superhero community, which seems already established in the DCU.
