James Gunn’s Challenge For Superman: Legacy

The head of DC James Gunn is already working on overdrive to create a new and improved look for the franchise and its films. Using the expertise that he gained from Marvel and the Guardians of the Galaxy films, Gunn aims to take DC to the next level. One of the biggest moves that elicited mixed opinions across fandoms was the ousting of Henry Cavill as Superman and the subsequent casting of David Corenswet.

A lot of these decisions that Gunn has made is seen as an effort on his part to reinvent the franchise starting with Superman: Legacy. According to the filmmaker, the movie will be a completely fresh take on the Man of Steel, which will be directed by Gunn himself. The DC head confessed to The Hollywood Reporter that he was not always enthusiastic to take on the celebrated superhero and his legacy owing to the challenges involved with exploring an iconic character.

“It’s easier to take a character nobody knows, like the Guardians, or Peacemaker, and then do whatever you want with them. People in every single country in the world know the story of Superman. How can I make it different from the movies that have been made so far, but also have it respect all the Superman movies that have been made so far?. So it just took me some time to try to figure it out”.

Gunn further added that true to the film’s title, his wish was to make a sincere superhero movie that will respect the legacy of Superman as portrayed in the earlier films by Zack Snyder. After Cavill’s exit as Superman, a lot will rest on Corenswet to live up to the reputation of DC’s biggest icon.
