10+ Celebs Fans Didn't Realize Were In These Movies

Yes, you may have seen the movies. You may have even registered a lot of what was going on.

But what you didn't realize is that there were some famous stars hidden in them.

Between cameos and short appearances, these are the celebs you didn't realize were in these famous films.

1. Natalia Dyer


Movie: The Hannah Montana Movie

Before she was in Stranger Things, she actually played the daughter of a stalker in The Hannah Montana Movie.

Huh, I honestly don't know which is creepier.

2. Brie Larson

Sony Pictures

Movie: 13 Going On 30

It seems that Brie Larson has been jumping around in time her whole career.

Before she was in the '90s as Captain Marvel, she was in the '80s as this mean girl on the far right.

3. Jack Gleeson


Movie: Batman Begins

Before we all despised him in Game Of Thrones, he was the "Little Boy" in Batman Begins.

Truly it was a career-defining role.

4. Mila Kunis


Movie: Honey, We Shrunk Ourselves

Who knew that Mila Kunis did things before she was in That '70s Show?

Well, you know now, because she was a teen in this movie from the Honey, I Shrunk The Kids franchise.

5. Scarlett Johansson

20th Century Studios

Movie: Home Alone 3

One of the least-watched Home Alone movies featured a really big up and coming star.

Scarlett Johansson played the mean older sister in that movie. I wonder how she feels about it.

6. Rami Malek

20th Century Studios

Movie: Night at the Museum

Before he was out winning Oscars and proving he could be an amazing actor, he was starting to prove that fact as Pharaoh Ahkmenrah in Night at the Museum.

7. Katherine Heigl

Universal Pictures

Movie: Bride Of Chucky

A lot of famous actresses have played the "final girl" role in horror movies.

But this is one that kind of went under the radar. This rom-com star went up against Chucky!

8. Steve Carrell


Movie: Sleepover.

It's hard to picture the bumbling, goofy Steve Carrell as a police officer, but you better believe that it happened.

It was a teen movie, so he probably was pretty goofy.

9. Christian Bale


Movie: Pocahontas

Believe it! One of the most prolific actors of our time was sneakily inserted into a Disney movie.

Right around the time he was doing American Psycho, no less!

10. Mary-Kate and Ashley Olsen

Universal Pictures

Movie: Little Rascals

Oh yes. These two made a ten-second cameo in little rascals as Darla's friends.

They were at her sleepover, and they were amongst the many saying "ugh, boys!"

11. Ben Affleck

Warner Bros.

Movie: Buffy The Vampire Slayer.

Before he was hunting after some good guy named Will, he was playing basketball alongside the rest of the cast of the Buffy The Vampire Slayer movie.

12. Elijah Wood

Universal Pictures

Movie: Back To The Future II

Way before he was nailing Frodo in Lord Of The Rings, Elijah Wood was a pretty prolific child actor.

He even had a part in Back To The Future II.

13. Joe Manganiello

Sony Pictures

Movie: Spider-Man

Oh yeah! The guy who made us all swoon in Magic Mike, in True Blood and in What to Expect When You're Expecting, was Flash in Spider-Man!

Weird, right?

14. Leonardo DiCaprio

New Line Home Entertainment

Movie: Critters 3.

You aren't born the greatest actor of our generation.

You need to work to get into the public eye, which is why Leo was in Critters 3.
