Late actorJohn Ritterwas the subject of ABC’sSuperstaron Wednesday night, and footage from the show reveals son Jason getting emotional speaking about his late father. FromThree’s CompanyandProblem Childto8 Simple RulesandBad Santa, Ritter had long been a fan favorite actor on both the big and small screen. Sadly, he passed away suddenly in 2003 due to an aortic dissection.

A one-hour documentary, ABC’sSuperstar: John Ritterpresented never-before-seen family videos along with unseen footage from a Barbara Walters interview. Also included were interviews with various names in the business who knew Ritter, like Jimmy Kimmel, Bryan Cranston, Kaley Cuoco, Henry Winkler, Suzanne Somers, and Raven-Symone.Jason Ritter, John’s son, also remembers his father in footage from the show, and he gets choked up remembering the “beauty” of his father’s life.

“He is acomedy genius. He was a very loving and supportive dad. I never felt like I was jealous that I had to share him with the world. One of the things that I try to do is look at his life. Instead of feeling like I was reading this beautiful book and all of a sudden the last ten chapters were ripped out, I started to look at it as, that was the whole book. That’s the whole story. And what’s the beauty in that. And there was so much beauty in his life.”

Ritter’s ex-wife Nancy, whom he was married to from 1977-96, was also featured in the program. She similarly has memories of, along with John, telling their children to “pursue what you want to pursue,” always supporting whatever it was that they wanted to do in life. As Nancy noted, John “made a good, conscientious choice to never say to his children, ‘Don’t, it’s too hard.'”

Once referred to by Don Knotts as the “greatest physical comedian on this planet,” Ritter became ahousehold nameby starring on the classic sitcomThree’s Companywith Joyce DeWitt and Suzanne Somers. That role earned him an Emmy and a Golden Globe in 1984.
