Billy Joel's career is so massive it requires a two-part documentary. Here's a look into the first half, which opened Tribeca Film Festival.

At one point, [Billy] said to me, 'You going deep?' And I said, ‘Yeah, and you know you’re going to go deep too,'" the film’s co-director Susan Lacy says.

The "Piano Man" singer said he got "punched in the nose, which I deserved," after telling his best friend Jon Small that he was seeing his wife, Elizabeth Weber.

Steve Cohen, who is executive producing the new documentary "Billy Joel: And So it Goes," said that his fingers are crossed that the 76-year-old will perform again after his brain disorder diagnosis.

Alexa Ray Joel watched the new documentary about her father, 'Billy Joel: And So It Goes,' with mom Christie Brinkley. The film premieres in two parts on July 18 and July 25, on HBO Max.

He didn’t see the film until it was finished, so he stuck by that, and we took that as permission to tell the real story about Billy Joel.”
