5 Marvel Movie Trailers That Gave Away Major Spoilers

It’s been a common complaint among moviegoers for decades: Movie trailers give away too much of the plot. Of course, you still have to actually see the movie to learn how much of the plot was given away, but the folks at Marvel Studios still tend to be a little less spoiler-happy in their trailers than a lot of other film companies. But that doesn’t mean they haven’t occasionally overplayed their hands, giving away plot information, action beats, and other treasures that may have been better experienced cold by first-time viewers. With that in mind, here are a few of the most egregious examples of Marvel movie trailers with major spoilers.

Obadiah Stane Is Iron Monger (Iron Man)

Spoilers are tricky to discuss when you’re talking about comic book movies, since anybody can pick up a comic and discover what many general audiences won’t know until they see the movie. But it’s clear watching Iron Man that the fact that Obadiah Stane, the character played by Jeff Bridges, is an enemy of Tony Stark’s is intended to be a surprise plot twist. The trailers were pretty clear that Bridges was playing a bad guy of some kind, though, eagle-eyed viewers were even able to spot a brief glimpse of the man in his Iron Monger armor, which wasn’t really a big part of the movie’s advance advertising.

Imagine, if you can, you’re sitting in the theater taking in Thor: Ragnarok for the first time. Imagine your excitement as, completely by surprise, Thor’s opponent in the armed combat arena that forms the setting for much of the action enters and turns out to be none other than The Incredible Hulk. Unfortunately, the Marvel people thought Hulk’s involvement in the movie was just too important to keep secret, so it was covered heavily in Ragnarok’s promotional campaign, including the trailers.

The Miniature Train Fight (Ant-Man)

Ant-Man represented something of a change in scale, if you will, for the Marvel Cinematic Universe, as viewers had become acclimated to seeing superheroes and villains leveling entire city blocks in their battles with one another. But since Ant-Man tends to fight his battles on smaller terrain, viewers were primed and ready for something a little different. Still, it seems like a shame that the clever final fight in the movie, set in a child’s model train set, was spoiled so thoroughly in the trailers.

Old Lady Skrull (Captain Marvel)

The first trailer for Captain Marvel was pretty cool. It depicted the film’s ostensible hero punching what appeared to be an innocent old lady in the face, which was pretty surprising to many viewers. Comic book fans knew that she was likely a shape-shifting Skrull, but to general viewers, it was just a superhero punching a random old woman. But in a classic case of Marvel losing its nerve, this tidbit was clarified in the second trailer for the film, which kind of took a lot of the fun out of the whole idea.

Tony Stark’s Death (Spider-Man: Far From Home)

When you’re dealing with a sprawling narrative across multiple movies, you can run into some unusual spoiler situations. That happened shortly after the release of Avengers: Endgame which, as the whole world now knows, ends with Tony Stark making the ultimate sacrifice to save the universe from Thanos. But when the first trailer for Spider-Man: Far From Home was released, there were still a few stragglers left who hadn’t seen Endgame yet, and if any of them happened to stumble upon the trailer, they would have known that Stark had died. Fortunately, Marvel took care to try and prevent that from happening, with video introductions warning people who hadn’t yet watched Endgame not to watch the Far From Home trailer until they had.
