- You may recognize Milo Ventimiglia for roles on "This Is Us,""Heroes," and "Gilmore Girls."
- He tells INSIDER his first Hollywood paycheck was on "The Fresh Prince of Bel-Air."
- He played a party guest that wandered upstairs with a girl.
- Ventimiglia says, at the time, he appreciated seeing the show's big star Will Smith making time to know everyone's name on set and treat everyone with respect.
- It's a lesson that stayed with him and he thanked the star for it years later when he saw him in real life.
Long before he was everyone's favorite father on NBC's tearjerker "This Is Us," Milo Ventimiglia appeared on one of the biggest TV shows of the '90s.
"My first real Hollywood paycheck was 'The Fresh Prince of Bel-Air.' I had one line when I was 18 and everything else that I had done in town, I'd done for free," Milo Ventimiglia told INSIDER.
Ventimiglia appeared on the show's sixth season at a party Ashley threw when her parents were away. His character, labeled "party guest," was seen near the end of the episode descending a staircase with a young lady.
When Ashley asks where the two have been, Ventimiglia's character plays it cool.
"Hey relax, Ash. We were just taking a little tour," he says before the couple strolls off laughing.
While Ventimiglia says it's fun to look back on, he said the show's star imparted an important lesson on him as a teenager.
"I got an opportunity to see Will Smith a few years ago and thank him for the way he was on set because who he is on set — he knows his crew's name, he treats everyone with respect, he's very talented, he does the work. He works hard," Ventimiglia said of meeting Smith years later. "He gave me, an 18-year-old kid who wanted to be an actor, a [look] at how the moving machine of a crew works and how inclusive you must be to support the crew and have the crew support you."
"He was one of the biggest movie stars ... but then also, you know, he was still a human being through the process of everything," he added. "He was a kind man to the crew and it was good to see that side of things and know that as big of a movie star and TV star and superhero as he was, he was still just a kind human being."
You can catch Ventimiglia on the season two finale of "This Is Us" Tuesday on NBC at 9 p.m. You can read about his transformation into an older Jack Pearson for the episode here.
