Todrick Hall wrote and recorded an entire album, Straight Outta Oz, and prepped a nationwide tour in mere weeks -- all of which is documented in Behind the Curtain: Todrick Hall. And in this clip, debuting on ET, he reacts to his record hitting No. 2 on the charts. "Further up the charts than we ever could have imagined," he tells ET.

The artist at No. 1? Beyoncé. "To say Beyoncé has inspired and influenced me is an understatement, so to be second on the charts only to my idol was one thing," Hall says, calling it "one of the most incredible moments of my life." "But to see the love and support of my fans was just a dream come true."

Behind the Curtain had its premiere at South by Southwest earlier this year, and ET spent the day with Hall ahead of a screening at Outfest this summer. "I sometimes think, Do people find this interesting?" he wondered. "Because this is my life every day and, you know, people could do this if they wanted to."

Talk eventually turned to Beyoncé at the time, too, while discussing his approach to his newfound fame. "You're always going to be a human being who needs human things and feels human things," he said. "I don't feel like Beyoncé is a human. This has helped me really put into perspective that she is just a person on the planet, living her life, who just has a special gift and was in the right place at the right time."

Here is the documentary's official synopsis:

"From small-town Texas to big-time show business, comes an inspiring documentary of grit, perseverance and the redemptive power of art. BEHIND THE CURTAIN: TODRICK HALL follows Todrick Hall as he launches his most ambitious project yet: the full-scale original musical, Straight Outta Oz. We watch him struggle to write songs about growing up gay and black in small-town Texas, his difficult relationship with his mom and the harsh realities of trying to make it in show business. With limited time and budget, the odds are against him, but Todrick's passion and his team of talented performers overcome all obstacles to bring this story to the world."

Behind the Curtain: Todrick Hall will be available digitally on Dec. 12 and on DVD on Dec. 19.
