Eric Roberts’ “Dancing with the Stars” debut Tuesday night offered a rare glimpse into the world of one of the most respected actors in the business.

The “Runaway Train” star’s latest TV appearances appear to be another step for Roberts to right the wrongs of the past, much of which he chronicles in his new memoir, “Runaway Train: Or the Story of My Life So Far.”

In the book, Roberts offered his sister, Oscar winner Julia Roberts, a “public apology” for words he once said about their famous family.

The “Righteous Gemstones” star made headlines in 2018 when he took responsibility for his sister’s award-winning career, in addition to his daughter Emma Roberts’ status in Hollywood.

“If it weren’t for me, Julia Roberts and Emma Roberts wouldn’t exist as celebrities and actresses, and I’m very proud of that,” he told Vanity Fair.

“I hope Julia will accept this public apology. It was an idiotic thing to say,” he wrote, according to People magazine.

His history in film and television roles is almost as extensive as his reputation when the cameras weren’t rolling.

“I hope Julia will accept this public apology. It was a stupid thing to say.”

“I wouldn’t be surprised if they suffered from PTSD when it was dangerous to be around me,” he admitted in the book about his bond with his sisters. “Lisa and Julia needed love and protection — instead they got fear and insecurity.

“The biggest consequence of my drug use was of course that I lost Emma.”

“I think I will be Julia’s brother and Emma Roberts’ father for the rest of my life,” he wrote. “I want to live up to that, to step aside with pride and grace. That’s one of the reasons for writing this book.”
