Mark Ruffalo Had No Idea Brie Larson Was In 13 Going On 30

Brie Larson (Captain Marvel) and Mark Ruffalo (Hulk) naturally became closer while making Avengers: Endgame.


So you'd think he'd know a little bit more about movies they had both starred in prior to this one, right? Apparently not, because Ruffalo had no idea he had actually been cast in a movie with Brie 15 years ago: 13 Going on 30!


The 2004 film just celebrated its 15th anniversary, which makes us feel a little bit old going on older.  Hilariously enough, Ruffalo, who co-starred in 13 Going on 30 alongside Jennifer Garner, had no clue he had appeared in the movie with Captain Marvel herself. She barely looks like herself in her "mean girl" getup, although it's certainly her, as you could visualize in the clip below.


The news broke whenever Ruffalo fielded a couple of questions at the Avengers: Endgame for Entertainment Tonight about whether he's his kids' preference Avengers, how it feels to finally visualize the ending of the Infinity Saga, and everything it means to him and the rest of the cast.


"By the way, did you realize that Brie [Larson] was in 13 Going on 30?" Asked Entertainment Tonight's reporter.


"She was a mean girl!" Laughed Ruffalo. "Oh my God! That's amazing."


"Wow, cool, I didn't know that," he gushed, immediately following the reporter informed Ruffalo that it was the role that inspired Larson to be a director.


The ET reporter then retrieved a photo to show Ruffalo, while the actor mulled over it in amazement, gushing over how it may really be Larson. Ruffalo's partner Sunrise Coigney joined in on the conversation, noting that the girl in the photo looked "a little" like Larson.


"It looks like her a lot. It’s her. How cool, I didn’t know that! We didn’t work with each other he lamented, though clearly impressed by Larson's early acting chops.


"That was a lovely little movie," he mused.


It looks like Larson's dream to be a director came true with the debut of Unicorn Store on Netflix, which hopefully Ruffalo actually does know exists. If not, maybe they require to get with each other for a little bit pow-wow session.


Avengers: Endgame drops into theaters on April 26.
