Charlie Sheen has opened up about his past mistakes during his time on “Two and a Half Men,” expressing regret over the fallout from his behavior, which has kept him and co-star Jon Cryer from communicating for over a decade.

Sheen’s struggles with substance abuse led to a very public breakdown and ultimately his departure from the popular CBS sitcom in 2011, leaving uncertainty among the cast and crew about the show’s future. His tensions with producer Chuck Lorre also strained his relationship with Cryer, who played the opposite lead. In a recently published interview with People, Sheen acknowledged his wrongdoings and reached out to former co-stars in a gesture of reconciliation.

“After seeing John’s honest and thoughtful remarks, I reached out and said, ‘I appreciate everything you contributed, and I’m sorry we didn’t connect personally,'” Sheen shared in the interview.

However, his message went unanswered because it was sent years later, and he no longer had the correct contact information for Cryer.

Reflecting on the passage of time, Sheen mentioned that his perspective has significantly changed after eight years of sobriety. He recently released his memoir, “The Book of Sheen,” and a Netflix documentary followed soon after. Cryer appears in the documentary and offers his candid insights into how Sheen’s struggles impacted him both personally and professionally.

Sheen acknowledged how his public issues derailed the comedy and disrupted Cryer’s career, expressing gratitude to his former co-stars for their honest portrayals in the documentary.

“Hearing his perspective was really fascinating,” Sheen remarked. “He was right there during all the chaos, and it affected him—his family, his career, everything. I can’t dispute anything he said.”

Cryer suggested that Sheen’s addiction stemmed from a lack of self-belief.

“He hit the nail on the head, and I’m glad he brought that up. It’s like he doesn’t think he deserves the success he has,” Sheen recalled. “That really struck a chord with me.”

Sheen likened it to being in a therapy session with Cryer, saying it evoked feelings from throughout his life where self-doubt loomed large. “I mean, I didn’t have any formal education or a plan; it just unfolded, and there was always this nagging voice saying it could all disappear at any moment,” he admitted.

Sheen commended Cryer’s insights as both “thoughtful” and “empathetic.” However, Cryer also expressed hesitance about discussing the hard times, worrying about reliving past emotions.

“I get that nervousness. It’s a recurring theme, but it’s not where we are today,” Sheen remarked. “We all make mistakes, and I do it every day.”
