In 1975, a 21-year-old kid from New Jersey almost walked away from the audition that would change television history. He needed money. Like, "I can’t pay my rent" kind of money. A Broadway show had offered him a steady paycheck, and for a struggling actor, that's usually the finish line.
But casting director Lynn Stalmaster saw something. He basically bribed the kid to stay in LA by getting him a tiny part in a horror flick called The Devil’s Rain just to "tide him over." That kid was John Travolta. The role he was waiting for? Vinnie Barbarino.
Honestly, looking back at Welcome Back Kotter John Travolta was the lightning in the bottle that no one—not even the show’s creator Gabe Kaplan—truly saw coming. The show was supposed to be about Kotter. It ended up being the Vinnie Barbarino variety hour.
The "Criminal" Audition and the Real Vinnie
The character we know wasn’t even Vinnie in the beginning. In the original "Kotter test" tapes from March 1975, Travolta is introduced as "Eddie Barbarino."

The swagger didn't come from nowhere. Travolta later told Gabe Kaplan that he based the character's "soul" on Robert De Niro’s performance in Mean Streets. He wanted that "you know you should stay away but you can't" energy.
It worked. Too well.
By the time the pilot was taped, Travolta was already ad-libbing. He started using the "What? Where? When?" bit, which the writers loved and immediately shoved into every script. But the producer, James Komack, hated it. He actually yelled at Travolta after the first taping, saying he was turning the "leader of the gang" into a "f-ing idiot."

History, and the Nielsens, proved Komack wrong. The audience didn't want a gritty gang leader; they wanted the dim-witted heartthrob who confused a baby with an elevator delivery.
Why the Show Actually Died
People usually blame the end of Welcome Back, Kotter on John Travolta’s ego or his movie career. That's a half-truth.
By 1977, Saturday Night Fever had made Travolta the biggest star on the planet. He was an Oscar nominee. He was a pop star with the hit "Let Her In." He was, quite literally, too big for a classroom in Brooklyn.
But the real rot started behind the scenes. Gabe Kaplan was in a massive contract war with the producers. By the fourth season, the guy whose name was in the title was barely there. He appeared in only eight episodes.
The Sweathogs were also getting... old.
- John Travolta was 25 by the finale.
- Ron Palillo (Horshack) was 30.
- Robert Hegyes (Epstein) was nearly 30.
It’s hard to sell a "remedial high school class" when the students look like they should be at their ten-year reunion. When Travolta checked out to film Grease, the show’s heartbeat stopped. The final season saw him downgraded to "Special Guest Star," appearing in just a handful of episodes before the show was quietly taken out back and put out of its misery in 1979.
The "I’m So Confused" Legacy
There’s a weird myth that Travolta hated his time on the show. In reality, he viewed the cast like a second family.
The tragedy is that the "Sweathog curse" hit almost everyone except him. While Travolta was dancing his way to a $20 million-per-movie paycheck in the 90s, his co-stars struggled. Ron Palillo’s famous Horshack laugh actually came from a dark place—he based the wheeze on his father’s final breaths during a battle with lung cancer. He never found another role that fit.
Robert Hegyes eventually became a real-life drama teacher, trying to give back to the craft that peaked for him in his twenties.
What to Do With This Nostalgia
If you’re looking to revisit the Welcome Back Kotter John Travolta era, don't just hunt for clips on YouTube. The show is a masterclass in 1970s multi-cam timing.
- Watch the "Follow the Leader" two-parter. It's the rare moment the show actually gets dramatic about Vinnie’s ego.
- Listen to the theme song by John Sebastian. It was originally just called "Welcome Back" because Sebastian couldn't find a word that rhymed with Kotter (he tried "slaughter" and "otter" before giving up). The song was so popular they renamed the show to match it.
- Check out "The Boy in the Plastic Bubble." It was a TV movie Travolta did while still on Kotter. It’s where he met Diana Hyland, the love of his life who tragically died of cancer while he was filming Saturday Night Fever.
The show wasn't just a sitcom. It was the launchpad for a cultural icon who defined three different decades of Hollywood. Even if the producer thought he was playing an idiot, Travolta knew exactly what he was doing.
