Iron Man At 18: The Movie That Built The MCU And Changed The Genre Forever

On May 2, Iron Man turned 18, meaning both it and the MCU have officially entered adulthood. We're looking back at the movie's impact and how, following its 2008 release, it changed the genre forever.

Over the weekend, May 2 marked the 18th anniversary of Iron Man's release in 2008. The movie was a game-changer for a genre that had, in the preceding decade, been a mixed bag at best. For every Spider-Man and X-Men, there were let-downs like Fantastic Four and Elektra. However, by taking a B-list superhero and making a truly great blockbuster, Marvel Studios successfully launched what would become the biggest franchise ever.

It's fascinating now to look back at the impact Iron Man had in 2008. Not dissimilar to today's superhero offerings, details of the post-credits scene leaked online in advance, confirming that Samuel L. Jackson would make a surprise appearance as Nick Fury to set the stage for The Avengers to assemble. Even with The Incredible Hulk scheduled for release months later, no one at the time believed it would happen, though the Jade Giant's movie did tee up the possibility of Tony Stark assembling a team to take down Bruce Banner's rageful alter-ego (an idea that was dropped when Joss Whedon took over writing duties from Zak Penn).

Thor and Captain America: The First Avenger started taking shape as Iron Man 2 touched down in theaters in 2010, but there was still a lot of scepticism surrounding the idea that Marvel Studios could bring together all these different superheroes in one movie for a full-blown team-up. It sounded impossible, and had all the makings of a complete mess. Fortunately, Whedon's The Avengers in 2012 marked a turning point for the budding MCU that would help eventually bring us movies like Guardians of the Galaxy, Captain America: Civil War, Avengers: Endgame, and Spider-Man: No Way Home. None of that would have been possible if Iron Man hadn't started it all with such aplomb.

For those of you who watched Iron Man on a big screen, we're sure you'll agree that it's a little hard to believe that children born that year are now adults. At 18, the MCU is also entering adulthood, and love or hate some of the movies, TV shows, and creative decisions made during that time, it's hard to deny that it's been one heck of a run for this franchise. 

Funnily enough, I was 18 when Iron Man was released. While it sounds a tad overdramatic to say the movie "changed my life," it would also do it a disservice to say it didn't. After a string of disappointments like Daredevil, X-Men: The Last Stand, Spider-Man 3, and Fantastic Four: Rise of the Silver Surfer, Iron Man led to a renewed interest in superhero fare, especially with Easter Eggs and post-credits scenes that teased an exciting shared world (they're common now, but at the time, even a vague reference to another superhero was enough to break the internet).

Less than a year after Iron Man was released, I signed up for this site and the rest, as they say, is history. Since then, I've interviewed countless superheroes, seen quotes from my reviews on Blu-ray cases and on television, and found a fulfilling, hugely enjoyable career path that's allowed me to write about the characters I've loved since childhood. And you know what, the Armored Avenger's movie deserves some credit for that. 

Far beyond this writer's personal life, Iron Man's impact is still being felt. After a hit-and-miss Multiverse Saga, Marvel Studios has enlisted Robert Downey Jr. to return to the MCU, albeit as the villainous Doctor Doom in Avengers: Doomsday. The effect it's had on fans and the genre can't be overstated, and as the wider franchise hits 18, it still feels like the best is yet to come, especially with the likes of Spider-Man: Brand New Day, Avengers: Secret Wars, and the X-Men reboot on the horizon. The crazy thing? One of those films might just inspire the next generation of writers, artists, or filmmakers to chase their passion.

Damn man , that’s crazy…

I was 13 when Iron Man came out and I still remember , my little brother really wanted to watch Speed Racer which would come out the following week so my parents took us a week later after IM hard come out to see both in that me and my dad went to go watch Iron Man while my brother and mom went to go see Speed Racer.

I honestly don’t remember the experience much except brief moments but when the ending came and Tony said “I Am Iron Man” following by the music & credits , It gave me a feeling of elation I hadn’t really experienced much beforehand in regards to superhero fare and it’s still a movie I am a big fan of till this day like many others.

Anyway regardless of how people feel about the MCU now , then or just overall since its inception , it’s hard to imagine my life without it or modern pop culture in general honestly and that’s all thanks to this film via Jon Favreau , RDJ aswell as the rest of the cast & crew!!.

If we're being honest, THE DARK KNIGHT did more to influence the genre then IRON MAN ever did. They debuted the same year too.

They impacted the genre in different ways. Dark Knight was more grounded and Iron Man was more unapologetic. Both great flicks that I saw in the theater multiple times.

Recently watched it again for the first time in a few years. Still holds up really well. Great mix of fun without being goofy with real stakes. The ending is a little wonky but not terrible. I remember hearing Coulson say just call us Shield and whispering to my brother "dude! That's the Avengers! Like Hulk and Thor!" But thinking that will never happen. Impossible. Now here we are.

I started reading Marvel comics in the 60's and into the 70's. Seeing that stuff fully realized was a goose bump moment. For me, when they did Vision as a comic accurate character was the moment that I knew that the nerds won.

it hasn't all been perfect but the good entries are still great and shows like Loki and Wonder Man expanded what can be done within the genre.

Make mine Marvel.

Brilliant film. We'd be lucky to get a superhero outing at 1/10 of its quality now

An absolute classic. I remember watching this in a shitty little theater in small town like 35 mins away from where I live because we were visiting my stepsister. I was so annoyed by the terrible projector quality and old seats but the moment the movie started I was completely transported and loved every second of it. The needle drop at the end was a perfect finish and it ironically is the reason I went from being an introverted nerdy kid in 9th grade to being the go to guy for superheroes and comic book characters in my school. If it wasn’t for this I probably never would have come out of my shell since now I talk to dozens of new people a day for my current job 🤷🏽‍♂️

People don't talk enough about how this film is a great film to show someone if they've never seen a CBM or if they claim they're 'not into those kinds of movies.' This film bridges that gap between reality and comic book story in such a subtle way that your wanting more by the end. It was smart choosing this movie to make first.
