James Gunn wrapped filming on “ Superman ” at the end of July, but there’s still plenty of work to be done on the 2025 comic book tentpole. Responding to fans on Threads, the writer-director said he’s not nearly finished with the movie that will kick start his new DC Universe. “Heck no.

Once you’re done shooting you’ve only just begun!” Gunn wrote in a message on Threads. “Still lots of editing, VFX, sound, and scoring to be done!” When one follower suggested there will also be a significant time spent on reshoots, which have become something of a staple on big Hollywood tentpoles, Gunn replied with a surprising revelation: “I don’t know. I’ve done a total of one day of reshoots on my past two films combined.

” Considering Gunn’s last two movies were comic book tentpoles, 2023’s “Guardians of the Galaxy Vol. 3” for Marvel and 2021’s “The Suicide Squad” for DC, it’s mighty impressive that he didn’t need a bulk of reshoots to get either film completed. One follower asked how he manages to reduce the need for reshoots, to which Gunn responded with six tips .

“1) Over-prepare,” Gunn answered. “2) Don’t start shooting until I have a finished script my whole team is happy with 3) Hire actors and department heads I know can do their jobs 4) Surround myself with people who will challenge me and not just yes-sir everything 5) Ask myself daily – are there any small imperfections in the script or what we’re shooting that might end.
