THE FANTASTIC FOUR: FIRST STEPS' Post-Credits Scene Has Leaked Online Following Recent Test Screenings

Following a test screening for The Fantastic Four: First Steps last night, the movie's post-credits scene has reportedly leaked online and it's a potential game-changer heading into Avengers: Doomsday...

As we reported earlier today, Marvel Studios held a public test screening for The Fantastic Four: First Steps in Los Angeles yesterday evening.

There are conflicting opinions about why it took place. Some believe it's a sign that the studio is concerned the movie won't resonate with audiences, while others are convinced that Kevin Feige is simply trying to figure out what fans want after Thunderbolts* underperformed at the box office (despite being one of the MCU's best-reviewed releases).

When a screening like this takes place, spoilers leaking online are inevitable. However, we didn't anticipate one of the post-credits scenes being revealed just shy of two months in advance of The Fantastic Four: First Steps' release.

Scooper @MyTimeToShineH has learned that the stinger features Sue Storm reading to her and Reed's son, Franklin. She gets up, and when she returns, finds Doctor Doom holding his mask and sitting next to Franklin. His face is never shown, but both the costume and mask are described as "very comic accurate." 

If we piece this together with what we already know, it seems likely that Doom does hail from the same reality as Marvel's First Family and perhaps kidnaps Franklin (who, in the comics, has the power to reshape and create realities). That might be what brings the Fantastic Four to Earth-616, not the destruction of their world. 

The insider also noted that former Captain America Chris Evans doesn't appear in the movie. They explain. "I know for a fact he filmed something so it was either cut or will be in the final version of the film."

A lot can change between now and July 25, and this is only one of the post-credits scenes. Marvel Studios has changed these and the endings of its movies weeks before they arrive in theaters, so it might be best to temper expectations for now.

For now, you can rewatch the latest trailer for The Fantastic Four: First Steps in the player below.

Set against the vibrant backdrop of a 1960s-inspired, retro-futuristic world, Marvel Studios' The Fantastic Four: First Steps introduces Marvel’s First Family—Reed Richards/Mister Fantastic (Pedro Pascal), Sue Storm/Invisible Woman (Vanessa Kirby), Johnny Storm/Human Torch (Joseph Quinn) and Ben Grimm/The Thing (Ebon Moss-Bachrach) as they face their most daunting challenge yet.

Forced to balance their roles as heroes with the strength of their family bond, they must defend Earth from a ravenous space god called Galactus (Ralph Ineson) and his enigmatic Herald, Silver Surfer (Julia Garner). And if Galactus’ plan to devour the entire planet and everyone on it weren’t bad enough, it suddenly gets very personal.

Paul Walter Hauser, John Malkovich, and Natasha Lyonne have been cast in mystery roles. Robert Downey Jr.'s Doctor Doom is rumoured to appear, though that's surely a given with Avengers: Doomsday on the way.

Director Matt Shakman worked with both Avatar: The Way of Water co-writer Josh Friedman and WandaVision's Cam Squires on The Fantastic Four: First Steps' screenplay, with Eric Pearson (Black Widow) later coming on board for a final polish.

The movie is set to be released in theaters on July 25, 2025.

I’m sure we all expected it to be a partial Doom reveal. Having him holding Franklin does add a layer of panic to the situation.

@FrankenDad - Any stranger appearing in your house while holding your newborn will send any parent into a panicked situation and state. I think something like that is easy to find relatable to ALL of us.

It is obvious that it will be Doom related.

I am also guessing they will shoot a long postcredit scene like in Thunderbolts because they have most of the cast in Doomsday together now

"Not the destruction of their world."...The fact that this was even in play as a possibility is pretty hilarious. Whats next? One of the Fantastic Four Die?

@BlackStar25 - I don’t see their world dying at all

Likely they will be integrated into the MCU as having been there since the beginning post SW

@TheVisionary25 - Thats!...More plausible then them retreating from a defeat in their first movie.

@BlackStar25 - yeah

I don’t see them suffering a defeat in their first film even if in universe they have saved the city a bunch of times now

@BlackStar25 - What do you mean? They're doing a story about multiverses and incursions. Why leave out the latter?

@HOTSHOT - Because that's not what films do in their first entries especially when trying to establish a property like Fantastic Four.

@BlackStar25 -
The film is set in a different reality, nobody gives a single frick about that reality - so having the spectacle of Galactus destroying Earth and us having a Fantastic Four who have a lot of personal trauma going into Doomsday, perhaps having Doctor Doom be a survivor from their world also who blames the Fantastic Four, would have been good for motivation and character development.

As it is, the film is just going to be generic and skippable. Absolutely meaningless to watch because nothing in it will be relevant for Avengers: Doomsday.

So Marvel is riding on "comic-accurate" Doom but the F4 wears pajamas? Ok
