Superman is full of twists, turns and unexpected scenes, including a series of celebrity cameos that will make every comic book lover happy.
Some fans were shocked to see Bradley Cooper make a cameo in James Gunn’s new superhero flick, which hit theaters on July 11, as the A-lister kept the role pretty tight-lipped – but he wasn’t the only big-name star to make an appearance.
Superman stars David Corenswet in the titular role, along with Rachel Brosnahan as Lois Lane and Nicholas Hoult as Lex Luthor, among the sea of DC Comics characters that were brought to life on the big screen.
This wasn’t Cooper’s first time being part of a comic book universe, as he previously starred in James’ Guardians of the Galaxy in the fan-favorite role of Rocket Raccoon.
