The Olsen twins weren't the only original "Full House" cast members who didn't return for its Netflix spin-off "Fuller House." But unlike their character, Michelle, this guy's character is in the new show, but it's the actor who's been replaced.

Hardcore "Full House" fans may remember Harry Takayama, Stephanie's friend from the family sitcom's second and third seasons. He was played by an eight-year-old Nathan Nishiguchi.

"The original Harry Takayama, who was one of Stephanie's friends in the early seasons — we wanted him to come back for an episode, but he wasn't able to come," the actress who plays Stephanie, Jodie Sweetin, told Business Insider. "So there is a guest spot of Harry Takayama played by a different actor. It's not the original Harry."

If you don't remember Harry, here's a hint: Stephanie refers to him as her husband on "Fuller House." That's because the two got married in an adorable backyard ceremony on the 1989 episode "Middle Age Crazy."

Fans watching "Fuller House" may think the original actor returned to the sequel, because the character shows up for an episode, and is greeted with cheers from a duped studio audience. But that's actually Michael Sun Lee.

Sun Lee took over the part on the episode titled "War of the Roses," in which the Tanner girls and best friend Kimmy Gibbler (Andrea Barber) find themselves at romantic crossroads and look back on the men from their past.

As for the original actor, Nishiguchi last appeared in a 1990 TV movie titled "Hiroshima: Out of the Ashes," according to IMDb. And according to Bustle, the 35-year-old San Francisco native doesn't have any social-media accounts.

So fans will just have to keep waiting for the old Harry Takayama.
