If you close your eyes and think of the most authoritative, slightly condescending, yet deeply loving voice in Hollywood history, you’re probably hearing William Daniels. It’s that crisp, Mid-Atlantic clip. The kind of voice that makes you want to sit up straighter and finish your homework, even if you’re forty-five years old.
Most people today know him as the legendary George Feeny. You know, the guy who lived next door to the Matthews family for seven seasons and somehow taught every single subject at John Adams High? Yeah, that guy. But looking at the full roster of william daniels movies and tv shows, you quickly realize Mr. Feeny was just the tip of a very large, very talented iceberg.
Honestly, the man has been the backbone of American entertainment for over seven decades. He’s played a Founding Father, a snarky supercar, a brilliant surgeon, and the father of a confused Dustin Hoffman. He’s basically the secret sauce of 20th-century pop culture.
The Role That Most People Actually Get Wrong
Before he was teaching Cory and Topanga about the value of friendship, William Daniels was a Broadway powerhouse. Specifically, he was the guy who defined John Adams in the musical 1776.
There’s a weird misconception that he was just "in" that movie. No. He was that movie. He played Adams on stage first, and then carried that "obnoxious and disliked" persona over to the 1972 film. It’s a masterclass in being a prickly protagonist.
You’ve got to love the irony here: a man who would later play a beloved mentor started his most iconic early role by singing about how everyone in Philadelphia hated his guts. If you haven't seen the film version of 1776, go find it. It’s surprisingly funny, and Daniels’ chemistry with Howard Da Silva (who played Ben Franklin) is pure gold.

A Career Built on Authority (and a Little Attitude)
There is a specific "William Daniels type." It’s the man who knows more than you do and isn't afraid to let you know it. Take his role in The Graduate (1967). He played Mr. Braddock, Benjamin’s father. He’s the physical embodiment of the "plastic" generation Benjamin is trying to escape.
Then there’s Dr. Mark Craig on St. Elsewhere. This is where he really flexed his dramatic muscles.
- The Show: St. Elsewhere (1982–1988)
- The Character: Dr. Mark Craig, a world-renowned but ego-driven heart surgeon.
- The Award: He won two Emmy Awards for this role.
- The Fun Fact: His real-life wife, Bonnie Bartlett, played his wife on the show too. They both won Emmys on the same night in 1986. That's a power couple move if I've ever seen one.
The Voice of a Generation (Literally)
Okay, we have to talk about the car. In 1982, a show about a man and his talking Trans Am premiered. Knight Rider was a massive hit, but William Daniels was nowhere to be seen on screen.
He was the voice of K.I.T.T. (Knight Industries Two Thousand).
The funny thing? He didn't even want credit for it at first. He felt that the car was its own character and didn't want his name to distract from that. He and David Hasselhoff didn't even meet in person until the show’s Christmas party months after they started filming. He recorded all his lines in a booth, often without the other actors even being there.

It’s a testament to his skill that he could build a genuine emotional bond with "Michael" through a speaker grill. K.I.T.T. wasn't just a computer; he was a partner with a dry, sophisticated wit that perfectly balanced Hasselhoff’s 80s machismo.
Beyond the Classroom: A Deep Catalog
If you dig into the archives of william daniels movies and tv shows, you’ll find some real gems that don't get enough love.
- The Parallax View (1974): This is a dark, paranoid political thriller. Daniels plays Austin Tucker. It’s miles away from the warmth of Boy Meets World.
- The Blue Lagoon (1980): Yes, he was in that! He played Arthur Lestrange.
- Captain Nice (1967): A short-lived superhero parody series where he played a shy police chemist who gains powers. It’s goofy, weird, and shows he could do physical comedy just as well as he did drama.
- Grey's Anatomy: Even in the 2010s, he was still crushing it as Dr. Craig Thomas, the mentor to Cristina Yang. It was a heartbreaking, beautiful arc that reminded everyone why he's the GOAT of mentors.
Why We Can't Quit Mr. Feeny
We have to come back to it. You can't talk about William Daniels without George Feeny.
Why did that character work so well? Because Daniels refused to play him as a "sitcom teacher." He didn't do "wacky." He was firm. He had high standards. He expected the kids to be better than they were, and because he expected it, they became better.
He’s the teacher we all wanted and the one some of us were lucky enough to have. When he gave that final "I love you all" in the series finale, it wasn't just a script line. It felt earned through seven years of stubborn, unrelenting guidance.

What to Watch Right Now
If you want the full William Daniels experience, I'd suggest this specific viewing order to see his range:
- Start with 1776: See him as the young, fiery, annoying revolutionary.
- Move to St. Elsewhere: Watch the ego. The brilliance. The way he handles grief and professional pride.
- Binge Boy Meets World: Obviously. But pay attention to the nuance. Watch how he uses silence.
- Catch his guest spot on The Simpsons: He reprised K.I.T.T. because the man has a great sense of humor about his own legacy.
Moving Forward with the Daniels Legacy
So, what do we do with all this?
First, appreciate the longevity. The man turned 98 in 2025 and is still widely regarded as one of the most professional, prepared actors to ever walk onto a set. He’s a bridge between the old-school theater world and the modern era of television.
If you’re a fan, the best way to honor his work is to dive into the stuff you haven't seen. Don't just stick to the reruns on Disney+. Look for his political work as President of the Screen Actors Guild, or find a copy of his memoir, There I Go Again.
Check out his work in Reds (1981) or his voice work in Superintelligence (2020). He’s spent a lifetime teaching us—sometimes through a chalkboard, sometimes through a red scanning light on a car hood—and the lessons still hold up.
Your next move? Set aside a weekend for a 1776 and Knight Rider double feature. It sounds like a weird mix, but it’s the only way to truly understand the sheer gravity of a career that defined multiple generations of American entertainment.
