James Gunn Avoids Reshoots with His Approach of Waiting for a Complete Script, Revealing Only One Day of Reshoots on His Past Two Movies

Filming for James Gunn’s Superman wrapped up at the end of July, yet work remains for the 2025 superhero film. On Threads, Gunn shared that the process is far from complete, stating, “Heck no. Once you’re done shooting you’ve only just begun! Still lots of editing, VFX, sound, and scoring to be done!”

Addressing a fan’s query about reshoots—a common element in large Hollywood productions—Gunn offered an intriguing insight: “I don’t know. I’ve done a total of one day of reshoots on my past two films combined.”

His previous two films were major comic book releases: Guardians of the Galaxy Vol. 3 (2023) and The Suicide Squad (2021). Gunn’s ability to minimize reshoots is particularly noteworthy given their typical prevalence in such high-profile projects. In response to a question about his approach, he provided six strategies:

1. Over-prepare.

2. Ensure the script is finalized and approved by the team before shooting begins.

3. Hire capable actors and department heads.

4. Work with individuals who offer constructive feedback rather than just agreeing with him.

5. Continuously assess and address any potential script or production imperfections.

6. Reiterate steps 1 and 2.Gunn detailed that casting involves a comprehensive process, including extensive auditions and background checks. For Superman, David Corenswet was cast in the role, known for his work in Ryan Murphy’s Netflix series The Politician and Hollywood, as well as Pearl directed by Ti West. Joining Corenswet are Rachel Brosnahan as Lois Lane, Nicholas Hoult as Lex Luthor, and a diverse cast including Skyler Gisondo, Anthony Carrigan, Edi Gathegi, Nathan Fillion, and Isabela Merced.
