The Actor Says Marvel’s Upcoming Blockbuster Makes Stranger Things 5 Look Small in Comparison

February 25, 2026: David Harbour is setting expectations sky-high for Marvel’s next cinematic event. The actor recently teased the scale of Avengers: Doomsday, suggesting the upcoming film dwarfs even the epic scope of Stranger Things 5.

“I thought that Stranger Things 5 was big,” Harbour reportedly said, hinting that Marvel’s production takes things to an entirely different level. His comment has quickly fueled excitement among fans eager to see how the Marvel Cinematic Universe plans to raise the stakes once again.

From Hawkins to the MCU

Harbour is no stranger to large-scale productions. After years portraying Jim Hopper in Stranger Things, he has been part of some of television’s most ambitious storytelling. The upcoming fifth and final season of the Netflix hit has already been described as cinematic in scope, featuring high production values and emotional intensity.

However, Harbour’s involvement in Avengers: Doomsday positions him within one of the most expansive franchises in film history.

In the Marvel universe, Harbour plays Red Guardian — first introduced in Black Widow. His character brings a mix of humor, bravado, and action to the MCU, and fans are eager to see how he factors into the larger Avengers storyline.

What Makes “Doomsday” So Big?

Marvel Studios has built a reputation for escalating scale with each Avengers installment. From global battles to multiversal stakes, each chapter expands the narrative canvas.

While official plot details for Avengers: Doomsday remain tightly under wraps, Harbour’s comment suggests that the film will feature massive set pieces, extensive ensemble casts, and high-intensity action sequences.

Compared to television productions — even ones as ambitious as Stranger Things — Marvel’s cinematic infrastructure operates on another level. Large sound stages, international shooting locations, groundbreaking visual effects, and interconnected storytelling across multiple films contribute to that scale.

Harbour’s comparison underscores just how expansive the next Avengers chapter may be.

A New Era for the Avengers

The MCU has entered a transitional period following the events of earlier Avengers films. With new characters joining legacy heroes, upcoming projects aim to redefine the team dynamic and overarching threat.

If Doomsday lives up to Harbour’s hints, audiences can expect a spectacle designed to rival the franchise’s most ambitious entries.

Marvel has long relied on ensemble chemistry and emotional stakes to anchor its blockbusters. Harbour’s involvement suggests that his character may play a more substantial role than previously anticipated.

Stranger Things vs. Superheroes

While Stranger Things 5 is already generating anticipation as one of Netflix’s most highly awaited finales, Harbour’s remark highlights the fundamental difference between premium television and billion-dollar film franchises.

Television offers extended character arcs and episodic storytelling. Marvel films, on the other hand, compress global stakes and explosive action into a theatrical event designed for massive screens and worldwide audiences.

Harbour’s experience navigating both worlds gives his perspective added weight. If he believes Doomsday surpasses the scale of Stranger Things 5, fans have reason to expect something monumental.

What Fans Can Expect

Though Marvel remains secretive about specific plot elements, speculation is already building around returning heroes, potential crossovers, and the introduction of formidable new villains.

The title alone — Doomsday — implies catastrophic stakes. Combined with Harbour’s teaser, anticipation is likely to intensify as production continues.

As of February 25, 2026, no official trailer or extended footage has been released. However, comments from cast members often signal confidence in a project’s ambition.

If Harbour’s statement is any indication, Marvel Studios is preparing a cinematic event designed to redefine scale once again.
