The Lego Movie star co-created the new Netflix show, in which he features as a self-help guru struggling with his own sobriety, and during a recent interview to promote the series, Will admitted he had actually relapsed while writing season one.

"As I was writing all this s**t on Flaked and I start shooting it, I started getting confused about where I was at," he told The Hollywood Reporter in March (16), when the show premiered. "Hardly anybody knows this... but I started drinking again."

Will did not share any further details about the setback, but in the interview, he insisted he had been clean for at least a few months and had started attending regular Alcoholics Anonymous meetings.

His candid confession resonated with a lot of fans and Netflix viewers, who have since reached out to Will to offer support and share their own sobriety battles, and the actor admits the public reaction really touched him.

"I gave a candid interview where I talked about when I was making the show, that I had my own struggles, after many years (of sobriety)," he explained on U.S. breakfast show Today. "Part of it was kinda delving into my own issues while writing, and while shooting, it was kind of life imitating art, imitating life, and a lot of fans reached out and said, 'Thank you for sharing your experience, it's a very authentic depiction of what it's like to go through it (relapse).'"

Will suggests he decided to go public with his relapse after butting heads with some critics who doubted the authenticity of his TV storyline.

"I kinda got into it with a few critics who said... 'This is not an accurate depiction of sobriety'," he recalled. "I was like, 'Hey, man, you can't be more accurate than this! I'm writing this as it's happening!' So for me, it (hearing fans' reactions) was very gratifying."

And the 46-year-old, who shares two boys with ex-wife Amy Poehler, is still enjoying hearing how opening up about his personal problems has helped others.

"It wasn't what I set out to do," he said. "I'm not saying anything new and I'm not trying to teach anybody a lesson, but the other day, I was at a restaurant in New York City and I was leaving with my friends, and... a waiter came out and said to me, 'I got 90 days (sober) and I watched Flaked, and that really spoke to me.' And he said, 'Sorry to bother you.' I said, 'Bother me? You just made my millennium!' So, it's gratifying."

Netflix bosses have since ordered a second season of the show, which Will and his writing partner, Mark Chappell, have just started work on.
