The Marvel Cinematic Universe has some of Hollywood’s most in-demand stars, and many actors in the franchise would be perfect for new hero or villain roles in the DC Universe. After directing some of the MCU’s best movies with the Guardians of the Galaxy franchise, James Gunn has left Marvel for DC. The director has already cast some MCU stars in the announced DCU projects, including actors like David Harbour, Maria Bakalova, Frank Grillo, and more.
