Way before he was Captain America or even Johnny Storm in Fantastic Four, Evans was not another teen star in this parody of She's All That, 10 Things I Hate About You, and all your other teen faves.

ScarJo might not be the star of Ghost World, but as Enid's sarcastic bestie Rebecca she makes being uncool very, very cool.

As if the actor who plays Captain Marvel doesn't already do it all, this comedy based on the graphic novel of the same name, has Larson showing off her vocals. Yes, this movie, which also stars fellow Avenger in Chris Evans, will take you down the Brie Larson was once a pop star rabbit hole.

Sure, this movie didn't come out until after he was officially Thor, but the horror-comedy written by Joss Whedon proved Hemsworth is a comedian at heart. And lucky for us, the MCU realized that too.

Yes, The Hurt Locker would be the obvious pre-Avengers choice for Renner, but it's this short-lived TV dramedy about a group of, yes, unusual NYC police officers might make you finally love Hawkeye. At the very least, you'll likely love seeing Renner team up with Amber Tamblyn.

Sure, she was amazing in Doctor Who, but it's the gone too soon Selfie that shows just how good Gillan is at morphing into different characters. Here, it's a self-absorbed Eliza Dolittle-type Instagram influencer.

Rewatch Parks & Recreation forever and always, but also watch the teen soap Everwood where this Chris played the adorable Bright Abbott, who goes from broody philandering football player to A+ boyfriend. Seriously, Bright and Hannah forever.

Holland became Spider-Man pretty early in his career, but before then he starred in the 2012 film The Impossible, a disaster drama about the 2004 Indian Ocean tsunami that shows he's been an expert crier since he was a little kid. No surprise, you'll be crying throughout the film, which also starred Ewan McGregor and Naomi Watts as his parents.

Well, I will: it's a drama that follows Gosling's Dan Dunne, a teacher with a cocaine problem, as he tries to save his student (Shareeka Epps) from following her absentee dad, played by Mackie, down a dangerous path. It's devastating and heartbreaking and definitely worth watching.

Cheadle plays one of the more serious Avengers, so it's only fitting that one of his most memorable roles is Basher Tarr in the heist remake Ocean's 11. Let's assume Rhodey wouldn't appreciate any of Basher's shenanigans — or his English accent.

Pro tip: watch while eating a Big Kahuna Burger for the full experience.

Some of the Avengers might be gone, but let's make sure their pre-MCU roles are forgotten anytime soon.
