These 21 Actors Were Huge Stars Hiding In Plain Sight As Side Characters In Movies You Love

Sometimes, an actor hasn't made it big yet. Sometimes, the cast is so loaded that an actor gets lost in the shuffle. And sometimes, my memory is awful, and I forget that well-known actors are in popular films.

A person dressed in period clothing says, "I sort of just... forgot," in a historical drama scene with elegant interior decor

Here are 21 actors that you (or at least me, myself, and I) probably forgot were in popular films:

1.Owen Wilson in Armageddon

A person with shoulder-length hair wearing a casual jacket is seated indoors, looking to the side

2.Rami Malek in Night at the Museum

Person wrapped in ancient-looking bandages, standing in a dimly lit, mysterious setting with hieroglyphics in the background

3.Kat Dennings in Thor

Person with glasses sits in a cafe, looking thoughtful

4.Glenn Close in Guardians of the Galaxy

An actor in a sci-fi uniform stands in a futuristic setting with large windows, appearing thoughtful

5.Keira Knightley in Star Wars: Episode I: The Phantom Menace

Person in elaborate headdress and robe leads a group of people in hooded cloaks, resembling a scene from a fantasy or sci-fi movie

6.David Tennent in Harry Potter and the Goblet of Fire

David Tennent as Barty Crouch Junior

7.Michael Fassbender in 300

A man with long wet hair smirks. The setting appears moody and dramatic, typical of a TV or movie scene

8.Lucy Liu in Chicago

Person looking surprised, wearing an elegant necklace in a dimly lit bedroom setting with a person in the background on a bed

9.Octavia Spencer in Spider-Man...and Drag Me to Hell

Woman with short hair smiles while sitting, wearing a patterned top. Background shows people on a set with equipment

10.Ryan Gosling in Remember the Titans

11.Daniel Craig in Lara Croft: Tomb Raider

A person in a jungle setting aims a rifle intently, appearing focused and alert

12.Colin Farrell in Minority Report

A person in a suit is looking through a translucent surface with a focused expression, possibly from a scene in a movie or TV show

Maybe you have not heard of Minority Report, but the sci-fi film starring Tom Cruise grossed $358M worldwide. Colin Farrell played a key role in the film, and I have no memory of him being in it.

Farrell has had a huge 2024 with the success of the HBO Max show The Penguin.

20th Century Fox

13.Alan Ruck in Twister

A man with short hair and a serious expression is in a cozy home setting, facing a person whose back is turned

Person operating a vintage television camera, looking through the viewfinder, with a focused expression

15.Matthew McConaughey in Tropic Thunder

A man with curly hair looks intensely in an office setting with a Vibe magazine cover framed on the wall behind him

16.Vince Vaughn in Rudy

17.Anthony Head in Sweeney Todd

18.Anthony Anderson in The Departed

A man in an office setting, wearing a shirt and tie, looks focused and attentive

19.Nick Offerman in Sin City

A person in a dramatic, snowy scene, wearing a quilted leather jacket, with an intense expression, set in a cinematic, noir-style atmosphere

20.Dave Chapelle in A Star is Born

A man in a sleeveless shirt and flat cap talks with another person outdoors

21.Oscar Issac in Robin Hood

A medieval king in a crown and fur cloak appears to be passionately speaking or shouting with an intense expression

To me, this list screamed, "I'm a '90s boy," so I'd love to hear from all the people in the BuzzFeed Community. Is there an actor you forgot was in a movie up until recently? Comment below!
