From the movie that kicked off the very notion of a cinematic universe to the movie that helped expand the subgenre’s level of inclusivity, these are the most important Marvel movies ever made. Spoiler alert, Howard the Duck isn’t one of them.
4) Spider-Man

Kicking off a cinematic franchise that continues to this day and will for the foreseeable future, Sam Raimi’s Spider-Man was a massive critical and commercial success in 2002. The early days of mainstream Marvel movies had already kicked off with X-Men two years prior, but this was the one that really sealed the comic company’s works as a majorly viable product.
There was a lot riding on Spider-Man. It’s hard to imagine a more beloved comic book character than webslinger, with only Batman giving him a run for his money. And Raimi knocked it out of the park, delivering a mixture of high-flying action, memorable set pieces, humor, and an endearing romantic connection between Peter Parker and Mary Jane Watson.

3) Iron Man

An MCU movie so important it’s still being directly referenced by the franchise to this day, Jon Favreau’s Iron Man remains one of the overarching universe’s most beloved entries. Like with Spider-Man, a lot hinged on the success of this film, perhaps to an even greater extent. If this one didn’t take off, there would be no cinematic universe (and given how it shot without a completed script, had a then-B-level title character, and a once-troubled lead star, its potential failure was quite possible).
Expanding on how the MCU hinged on Iron Man‘s success, there’s a larger way of looking at that. Naturally, Marvel’s cinematic universe wouldn’t have come into existence were this movie to have failed. Furthermore, given how other studios have since turned their owned IPs into cinematic universes, it’s quite fair to say that Iron Man changed the entire film industry’s prioritization. It wasn’t enough to just make a successful movie anymore, the goal was now to create a movie that was both profitable and could lead into sequels, spin-offs, and other movies set under the banner it’s positioned under.
