I’m not sure whether to count Steve Carrell: he was appearing in a Woody Allen film, and stealing scenes in BRUCE ALMIGHTY and ANCHORMAN, well before starting his famous run on THE OFFICE – but he’d done plenty of television work before that.
But his first on-screen work was apparently a small movie role – so if you’re fixing to disqualify him on a technicality, maybe qualify him on a technicality instead.
James Gandolfini had small roles in over a dozen films – including some pretty big movies, like CRIMSON TIDE and GET SHORTY – before he started working on television in general and playing Tony Soprano in particular.
Would Cybil Shepherd count? She was the female lead in The Last Picture Show (her first acting role) and had a supporting role in Taxi Driver, but at least for people my age is much better known Moonlighting and her sitcom Cybil.
Jane Lynch has had a long career in both movies and TV, and until about five years ago was probably best known for supporting roles in Christopher Guest mockumentaries and in The 40 Year Old Virgin. She’s much more famous now die to her role as Coach Sue on Glee.
Speaking of which, Craig T Nelson had lots of small movie roles before Coach.
How bout Anthony Edwards? In the '80s, he’s the other other guy in Top Gun; he’s the stoner in Fast Times At Ridgemont High; he’s a Revenge Of The Nerds nerd; he’s second banana under everyone from John Cusack to Timothy Dalton to Beau Bridges; and then comes his career-defining role on ER.
Tom Skerritt. He did lots of character work in movies and even had a lead in a major hit film* – which did nothing for his career. But being cast as Jimmy Brock in Picket Fences won him an Emmy and got him noticed.
*MASH. He played Duke Forrest. Who was Duke Forrest? The guy who was left out of the TV show, even though he was equal to Sutherland and Gould in the film.
After playing Sally Field’s husband in Punchline, and Nicolas Cage’s old prison buddy in Raising Arizona, and a whole bunch of movie cops, and yet other roles in films headlined by Walter Matthau or Kirk Douglas or et cetera, John Goodman became famous as Dan Conner on Roseanne.
About any working male actor in the 50s and early 60s probably put some time in on horseback. And many later well known actors put in some time in those live anthology dramas on tv in the 50s and 60s too. Isn’t the progression generally bit parts to supporting parts to lead roles?
Dennis Franz had small parts in plenty of movies before he became TV’s go-to actor for cops from HILL STREET BLUES to NYPD BLUE and beyond. (And, come to think of it, Dann Florek was kind of all over the place in big-screen supporting roles before his four-hundred-episodes-and-counting run on LAW & ORDER incarnations.)
Shifting gears entirely, I figure Ty Burrell’s a celebrity not from his performances in BLACK HAWK DOWN or DAWN OF THE DEAD – and not from playing Nicole Kidman’s husband in FUR, or spending film after film after film in Edward Norton’s shadow, or whatever – but from his Emmy-winning role as Phil Dunphy after all of that.
Except for child actors and standup comedians, I would think you could probably say this is true of more TV stars than not. Most actors are going to do grunt work in film at some point.
I think one good counter-example to this thread’s premise is Jim Carrey. He’d been in films and not making it big, then finally landed a star role on a sorta cult TV show – The Duck Factory – which got wiped from everyone’s memory.
He appeared in the film Earth Girls are Easy, but was billed way down. Even when Comedy Central ran it, they didn’t mention that Carrey was in it in the advertising.
He started getting recognition on the TV series in Living Color, finally, but he really hit it big in movies with the Ace Ventura films
He starred in The Mephisto Waltz and The Paper Lion (where he played George Plimpton) before M.A.S.H. Maybe not huge films, but he definitely wasn’t a Bit Player
Those are from memory. iMDB and Wikipedia list other roles.
