Superman Soars in James Gunn's Test Screenings: Runtime and Reactions Revealed By Jeff Sneider!

The DC Universe is gearing up for a seismic shift, and all eyes are on James Gunn’s Superman, set to hit theaters on July 11, 2025. Recent buzz from the James Gunn's Superman test screenings has fans buzzing with excitement, thanks to a glowing report from insider Jeff Sneider.

Shared via ComicBookMovie.com on March 18, 2025, this update not only unveils the film’s current runtime but also teases a potential casting surprise that’s got everyone talking.

Sneider’s latest scoop offers a promising peek into the Man of Steel’s return. With a mix of fresh reactions and intriguing details, here’s everything you need to know about this highly anticipated reboot.

What’s the Runtime of James Gunn’s Superman?

According to Sneider’s report in The InSneider newsletter, the current cut of Superman clocks in at a robust 2 hours and 20 minutes. This runtime places it in the sweet spot for a superhero epic—long enough to dive deep into Clark Kent’s world but concise enough to keep audiences engaged.

For context, it’s just shy of Gunn’s Guardians of the Galaxy Vol. 3 (2 hours 30 minutes) and Zack Snyder’s Man of Steel (2 hours 23 minutes).

This duration suggests a film packed with action, heart, and Gunn’s signature flair, balancing spectacle with character depth as the DCU kicks off its new era.

How Are Test Screenings Shaping Up?

The James Gunn's Superman test screenings are generating some serious positivity. Sneider spoke with a source who’s seen the film and “really liked it,” praising David Corenswet’s performance as Superman. The insider highlighted how the “jokey moments”—previously a point of contention—work seamlessly within the film’s flow, drawing comparisons to Gunn’s The Suicide Squad. “It has genuinely funny moments, but it also knows when to drop the shtick and get serious,” they noted.

This balance of humor and drama could be the secret sauce that sets Superman apart, offering a fresh yet respectful take on the iconic hero.

Has Jennifer Holland Joined the Cast?

Here’s where things get juicy: Sneider’s report speculates that Jennifer Holland, Gunn’s wife and a recurring collaborator (Peacemaker, The Suicide Squad), might have a cameo in Superman. While unconfirmed, her potential involvement wouldn’t be a shock given their creative partnership. Could she pop up as a Daily Planet staffer or a surprise DC character? Fans are already theorizing.

The cast is already stacked with talent—David Corenswet as Superman, Rachel Brosnahan as Lois Lane, Nicholas Hoult as Lex Luthor, and more—so a Holland cameo would be icing on the cake.

Why Does This Report Matter for the DCU?

With multiple test screenings under its belt, Superman is shaping up to be the cornerstone of the DCU’s reboot. Sneider’s glowing feedback contrasts with earlier mixed buzz, signaling that Gunn is fine-tuning the film to hit all the right notes. The trailer’s record-breaking 22.6 million views in 24 hours further proves fans are hungry for this vision.

As the first live-action film under Gunn and Peter Safran’s DC Studios banner, its success could set the tone for everything from The Brave and the Bold to Supergirl: Woman of Tomorrow.

Up, Up, and Away: Superman’s Bright Future

The latest from the James Gunn's Superman test screenings paints an optimistic picture—a film that’s long enough to soar, funny enough to charm, and serious enough to inspire.

With a runtime of 2 hours and 20 minutes and a cast that might include Jennifer Holland, this reboot is poised to redefine the Man of Steel for a new generation.

Come July 11, 2025, we’ll see if it truly flies higher than a speeding bullet—or if it’s just a bird or a plane after all.

For now, the buzz is undeniably super.
