Multiple Oscar nominee Will Smith is opening up about his mental health for his new fitness docuseries Best Shape of My Life, sharing that at one point he contemplated suicide.

The six-part YouTube Originals docuseries chronicles the King Richard star’s efforts to lose 20 pounds in 20 weeks and “get into the best shape of my life.” But the show, which he shot while working on his memoir, Will, offers deep look into the Hollywood A-lister’s life and mental health as an entertainer.

“When I started this show, I thought I was getting into the best shape of my life physically, but mentally, I was somewhere else. I ended up discovering a whole lot of hidden things about myself,” Smith says in the trailer.

In the trailer, Smith is seen working out, and writing his book, which he says is “exposing my life and so many things that people don’t know about me.”

Sitting around a table with his family, the actor mentions “the only time in my life that I ever considered suicide.”

“Now I’m about to show the world how little I know about myself,” he says. “What you’ve come to understand as Will Smith–the alien-annihilating MC, bigger-than-life movie star– is largely a construction. A carefully crafted and honed character designed to protect myself. To hide myself from the world.”

The docuseries is produced by Smith and Pinkett Smith’s  company, Westbrook Media, which is behind the Facebook Watch series Red Table Talk.

 The first two episodes of Best Shape of My Life will debut Monday, Nov. 8, one day before his memoir hits shelves.

The remaining 4 episodes will premiere daily on Will Smith YouTube channel.

Best Shape of My Life is co-run by Westbrook’s Lukas Kaiser and co-run and directed by Dexton Deboree (Unbanned, Promiseland).

The five-day docuseries event is Smith’s second collaboration with YouTube Originals, the first being Will Smith: The Jump.

 The charity event saw the actor bungee-jump from a helicopter over the Grand Canyon for his 50th birthday in 2018.
