According to IMDb, Onorati was in Cop Rock, Civil Wars, Murder One, Everybody Hates Chris, S.W.A.T., and Murder in the First.

Onorati has also appeared in The Rookie, Elementary, 2 Broke Girls, Blue Bloods, and The Big Bang Theory.

Who is Stanley to Jack in ‘This Is Us’?

As mentioned, Jack and Stanley have a complicated relationship on This Is Us. Throughout the years, fans watched as Stanley’s alcoholism destroyed their family. Then as Jack got older, he didn’t want his father to know anything about his new life, including Rebecca (Mandy Moore) and the kids. Stanley was also physically abusive toward his wife, Marilyn (Laura Niemi), before Jack helped her move out.

Meanwhile, Jack’s strained relationship with his father continued until Stanley’s death. But in This Is Us Season 3, Rebecca visited Stanley on his deathbed at a nursing home. And ultimately, the Pearson matriarch revealed that Stanley didn’t ruin Jack, who ended up becoming a great father to the Big Three.

Now, it seems Stanley will return for another run in This Is Us Season 6 Episode 4, “Don’t Let Me Keep You.” The previews confirm that the next new episode is all about Jack and Marilyn. But Stanley will also be making an appearance.

Ahead of the Jan. 25 episode, the This Is Us Twitter account retweeted a post shared by Onorati. The actor shared a photo of Stanley on the phone, and he hinted that the character will be back.

“Don’t miss tonight’s amazing episode of This Is Us written by Elan Mastral and a great episode for Laura Niemi but don’t blink or you might miss Stanley,” Onorati wrote.

Given Stanley’s history with Marilyn and Jack on This Is Us, we’re not sure how this one’s going to play out. But whatever happens in season 6 episode 4, it’s going to be emotional. Get ready.
