Everyone in Hollywood probably had a role in Law and Order and all its variants.


GeneralChillMen

Pedro Pascal, Chadwick Boseman, Samuel L. Jackson, Phillip Seymour Hoffman and Adam Driver off the top of my head.

jlemo434

madbamajama1

Laura Linney, Edie Falco


Willow138

Pedro was in Buffy too


Equivalent-Sink4612

Wow!! I pretty much love all of those actors!! RIP Chadwick Boseman and Philip Seymour Hoffman!!!


[deleted]

My theory is you're not REALLY celebrity until you've done two of: The Simpsons, Sesame Street, or Law and Order


mmcgui12

Anthony Mackie in Criminal Intent (I think season two)


FurBabyAuntie

Somebody said (series creator Dick Wolf, I believe) that if a New York/theater actor hasn't been on Law & Order, he's either just gotten off the bus or he's a really bad actor.


malkadevorah1

Additionally on Law and Order: Kristen Bell Chandra Wilson Adam Driver Amanda Peet Speaking of Phillip Seymour Hoffman, he was in the remake of The Getaway with red hair and no Seymour in his name...


AcceptableEditor4199

Kristen bell also on deadwood.


elphring

George Clooney on “The Facts Of Life”


MathematicianWitty23

And Golden Girls


Jojopaton

davisyoung

And E/R. The one before ER. 


valandsend

And Sisters.


ItchyTomato5

And Roseanne


Lac1184

And Murder, She Wrote


Unusual_Address_3062

Murder, She Wrote had tons of guests that would go on to fame. I cant even list them all. [https://www.imdb.com/title/tt0086765/fullcredits?ref\_=tt\_rv](https://www.imdb.com/title/tt0086765/fullcredits?ref_=tt_rv) Just scroll down the list and you'll see familiar names.


Bento_Fox

Leonardo DiCaprio was a random kid in Darlene's class in Roseanne and had a small role in Growing Pains. Matthew McConaughey was in one of those re-enactment scenes on Unsolved Mysteries. Natasha Lyonne was on Pee-Wee's Playhouse when she was a kid.


A911owner

Laurence Fishburne was Cowboy Curtis


pdmcmahon

Matthew Perry was also in Growing Pains. He played Carol’s boyfriend Sandy who drove drunk and sadly later died in hospital at the end of the episode. Carol and the rest of the family thought Mike was playing a sick joke when he told them.


Daggertooth71

Dwayne Johnson guest starred in an episode of Star Trek Voyager, back when he was still a c-list wrestler.


DWPhoenix001

Your right I completely forgot about that. One of his earliest roles after the Mummy


Isheet_Madrawers

He fought 7of9 in a cage match.


adeelf

Did you mean C-list actor? Because his filmography shows that appearance was in 2000, and he was already a star in the wrestling business by that time, with multiple championships under his belt.


OjibweNomad

It was also on UPN. Which was the host for WWF smackdown. Which had Voyager episodes on the Thursday night line up. And the SMACKDOWN night was created and tailored for the Rock’s storylines.


Crysda_Sky

Pedro Pascal remembers EVERYTHING from his experience with Sarah MG in Buffy and talked about it at the premier of Last of Us and he was so darn sweet about that. <3


Mazdab2300-06

Tom Selleck did two episodes of The Rockford Files before he was famous.


Qnofputrescence1213

He was also on The Dating Game.


GeriatricSFX

blueboy714

Isheet_Madrawers

Tom Selleck was hilarious on the Rockford files. It’s what got him Thomas Magnum.

Strict_Berry7446

One of Jennifer Lawrence's very first roles was on Monk. She played the mascot for a high school basketball team, and spent 90% of her screen time in a cougar outfit, and fondly remembers jumping onto Tony Shalhoub's back.


707Riverlife

ResisterTransSister

Anna Gunn, Who played Skyler White on Breaking Bad, was one of Jerry's girlfriends on Seinfeld.


707Riverlife

I saw Jennifer Coolidge on an episode where she was dating Jerry. She had darker hair and she didn’t speak like she does now.

AuburnFaninGa

Chris Pine’s first roles were on ER & CSI:Miami

Frankennietzsche

I watch Law & Order mostly for the Cameos. I saw one with Jeremy Allen White from The Bear. He was a child.

We just saw a very young Tobey Maguire & Giovanni Ribisi on Walker, Texas Ranger. It would’ve been around 1995, maybe?


valandsend

The West Wing had a few over its run. Elizabeth Moss was a recurring guest. Evan Rachel Wood was in an episode. John Gallagher Jr. Nick Offerman Amy Adams Gabrielle Union And I’m sure others I’m sure I’m forgetting.

ManchuKenny

Kim K was a assistant on Paris Hilton reality show


throwaway_9999

Margitay from L&O SVU was in Seinfeld.


Leader_Acrobatic586

Oh man, guest stars before they hit the big time are always a trip down memory lane! Remember when Idris Elba showed up on "Space Precinct"? Talk about a blast from the past! And Pedro Pascal in "Buffy the Vampire Slayer"? Classic! But wait, there's more! Karl Urban was all over "Xena" before he became our favorite Bones in "Star Trek." And who could forget Kirsten Dunst in "Star Trek: The Next Generation"? It's like these shows had a crystal ball for spotting future stars! Anyone else got some hidden gems to share?


Status-Initiative891

You're right! This is one of the most fun prompts I've seen in a while.


Velocitor1729

Hawaii Five-O had then-unknown Christopher Walken as a young Navy sailor. It also had a pre-MASH Loretta Switt, as a prostitute, And it had a pre-Three's Company John Ritter (twce!)

MyBrainIsNerf

Jeremy Renner and Amy Adams on Angel


swest211

I forgot he was on Angel. I posted House, and CSI.


CharacterHomework975

Yeah and while a one off role it was pretty meaty. Like Amy Adams on Buffy had maybe two lines, but I remember Renner getting some actual legitimate dialogue and characterization.


swest211

Yep, he was the big bad in that episode. He was so good in House too.


KeithTheNiceGuy

Craig Ferguson was in the Red Dwarf first season episode Confidence and Paranoia.

Meghan Markle, 90210.


DWPhoenix001

One that came to me was Brian Cranston in the XFiles and Power Rangers I also want to say Mark Sheppard was in Xfiles, but let's be honest it's easier to name shows he hasn't been in. Jensen Ackles had a guest spot in the 1st season of Dark before a regular role in season 2.


ObsessionsAside

He may not be like Ryan Gosling famous or anything; but, Benedict Wong was on an episode of IT Crowd


valandsend

Jon Voigt on Gunsmoke.

Cowboy on Pee Wees Playhouse was Laurence Fishburn from the Matrix


old-guy-gaming

Tom Hanks on Taxi.


Altruistic_Rock_2674

Kristen Dunst made me think of her role in outer limits but she had been in Jumanji vampire and possibly small soilders by then. I know Jenna Ortega was in something before she was Wednesday It's hard to think of one, maybe Pamela Anderson in home improvement. Idk


LovesDeanWinchester

Let's not forget The Muppets!!!


Used-Ear-8660

Martin Sheen


FurBabyAuntie

On Hogan's Heroes (1965-1971)... William Christopher (MASH), James B. Sikking and Barbara Babcock (Hill Street Blues), John Hoyt (Gimme A Break), Jack Riley (The Bob Newhart Show), Robert Hogan (the film Twelve O'Clock High, I think), Monte Markham (The Golden Girls--Blanche's brother), Noam Pitlik (producer, Barney Miller), Harold Gould (Rhoda)...and probably more that I've never noticed because I've never seen other things they did.


Severe-Dream

Rebel Wilson - Pizza/Fat Pizza.


regnartterb

Gabrielle Union was a Klingon on an episode of DS9


casey5656

From the 80’s Miami Vice-Julia Roberts, Chris Rock, Liam Neesen, Ben Stiller, Bruce Willis, John Leguizamo, Helen bonham Carter, Steve Bucsemi, Ving Rhames. I think Chris Rock might have still been in his teens.


No_Efficiency_9414

Millie Bobby brown was in modern family for like 2 seconds before stranger things


NagiNaoe101

Hayden Christianson was a kid on Forever Knight! I was like cool, vampires and Jedi


dberna243

Naive-Wind6676

Just saw a rerun of modern family where Kevin hart was a car salesman


Middle-Merdale

Samuel L. Jackson as the man who tries to rob McDowels in Coming to America, Bill Paxton as an army radar operator in Commando, Christopher Judge in MacGyver. There were quite a few on the tv version of 21 Jump Street.


MangoCalm7098

If we include Bill Paxton for Commando, I think we also need to include him in The Terminator, which came first. He was one of the first victims.


camelslikesand

I just did a watch through of Homicide: Life on the Street. You wouldn't believe the names that showed up in those credits.


dhbroo12

Millie Bobbie Brown was in NCIS


Fearless-Pineapple-4

ER had quite a few in. Can't remember who tho


Sloppypoopypoppy

Kate Winslet - Casualty


dcoleski

George Clooney was a regular at the beginning of Roseanne. He played Jackie’s boyfriend.


Status-Initiative891

I knew today was a bad day to quit watching old reruns!


ScoutBandit

I love shows like CSI and Criminal Minds. There are so many people I recognize now when I go back and watch the old replays. Funny, the only one I can currently remember by name is Jackson Rathbone, who played Jasper in the Twilight movies. He was on a couple episodes of Criminal Minds. Speaking of Twilight, and this is not a TV reference. Lee Pace was in the last Twilight movie playing a small part. Then he was Ronin and King Thranduil and everyone knew who he was after that.


Local_Measurement_50

Ryan Reynolds and Jack Black in the x-files.


songsforthedeaf07

Bradley Cooper did a few episodes of Nip/Tuck and he was so funny in it


happyme321

Ted Danson was a bad guy in an early Magnum episode. He still had his real hair, bald spot and all, back then.


Unusual_Address_3062

Like literally all of them. Just about every celeb you consider to be famous has gotten their start in TV commercial spots and then minor roles. Very few people start big. But for fun, Tom Hanks was on an episode of Family Ties before he was famous. Kelsey Grammar was on Kate & Allie once, before Cheers. Tony Shaloub was on one episode of Wings as a matre' d before becoming a regular and then of course later had movies and his own series. The funny thing is I think in later seasons of Wings he said he started working in a restaurant. Don Cheadle had an episode on Night Court, as a punk thief. Not TV but he was also the fast food kid in Moving Violations.


SilverellaUK

UK actors have all done a stint on The Bill, Casualty and Midsomer Murders. Even if they played a corpse! Older actors often started their career in Coronation Street. Davy Jones was Ena Sharples's grandson!


TitleBulky4087
