Mark Ruffalo Hints at Possible Hulk Return in Spider-Man 4 Mystery

Mark Ruffalo has sparked excitement about the potential return of the Hulk to the Marvel Cinematic Universe in 2026 with the upcoming film Spider-Man: Brand New Day. The new Spider-Man installment, part of MCU’s Phase 6, is currently in production, marking Tom Holland’s return as Peter Parker within the evolving franchise.

Filming began in early August under the direction of Destin Daniel Cretton, known for Shang-Chi and the Legend of the Ten Rings. Despite limited details about the plot, it is reported that an original Avenger will join Holland’s new Spider-Man adventure, fuelling speculation about which familiar face might appear.

In a recent interview with ET Online, Ruffalo was questioned about headlines suggesting he would reprise his role as Bruce Banner, the Hulk, in Spider-Man: Brand New Day. At 57, the actor responded with cautious optimism and a hint of excitement but avoided confirming anything outright.

“I don’t know, I’m still waiting to hear. I haven’t read a script yet. Well, if it does happen, it would be [Laughs] incredible. I grew up with this, and it’s changed my life in the best ways. Each time, it’s a new director, a new world, and it’s so exciting. There’s nothing else like it. A TV show doesn’t change its world from one director to the next, and that’s what is exciting.”

Interpreting Mark Ruffalo’s Comments on His MCU Role

Ruffalo’s vague statements are typical of Marvel actors who often maintain secrecy due to the studio’s strict confidentiality rules surrounding upcoming projects. The absence of any direct denial suggests that Ruffalo’s involvement remains intact but heavily protected from public disclosure.

The fact that he has not yet seen a script likely indicates plans to film his scenes later in the schedule. Marvel is known for imposing rigorous security on scripts to prevent spoilers, distributing them only when absolutely necessary. This approach helps explain his tentative remarks and lack of concrete information.
