CLEVELAND — After six weeks, Superman has left Cleveland. Well, the film crew, directors and actors have left Cleveland. 

The production for the new movie starring the popular DC Comics superhero had been filming in the city the past couple weeks, causing road closures and significant public interest and excitement. Parts of downtown had even been turned into the iconic "Metropolis" of the comics. People lined the streets as film crew security blocked off various areas around the filming.

The film's director, James Gunn, posted on the social media platform Threads, expressing his thanks to Cleveland and its residents as they leave the city. He said there were dozens of times Clevelanders stopped him in the street to let him know that they were grateful the movie was being shot in this city. 

"The wonderful background actors on the film were always so fun and funny and they clapped after takes, something that reminded us Hollywood cynics why we make movies in the first place," he wrote. "The pride you feel in being where Jerry and Joe first created Superman was invigorating. You exemplify his spirit. But just as much it’s the pride you have in your community, your hometown, your radio stations and restaurants and gathering places that touched me.

"Every city would be so lucky to have people that loved their city as much as you. You simply couldn’t have been more wonderful, kind, or accommodating to me and our performers and crew. Thank you a thousand times over for being our friends and partners on this film. Much love to you all."

The character of Superman has a close tie to the City of Cleveland.

According to Case Western Reserve University’s encyclopedia of Cleveland history, the character was created in the 30s by Glenville High School students Jerry Siegel and Joe Shuster.
