It’s a look at Bill Gates we’ve never seen. It’s a look “Inside Bill’s Brain” as the first trailer for the upcoming Netflix docuseries was released on Thursday.

From Academy Award winning director Davis Guggenheim (“An Inconvenient Truth,” “He Named Me Malala”), the three-part series is an “in-depth and unfiltered” look at the Microsoft co-founder and billionaire philanthropist’s life.

From his childhood to his rise at the Redmond, Wash.-based software giant to his pursuit of solutions for the world’s most pressing problems, the trailer looks like just what we would want out of documentary on such a unique personality.

The 2 1/2-minute clip opens with Gates answering a series of rapid-fire questions, including “what’s your favorite food?” Hamburger, of course.

As for his biggest fear?

“I don’t want my brain to stop working,” Gates says.

Cue the dramatic cello, as we watch Gates’ eyes flit from side to side across computer screens, images show his voracious note taking, and his wife Melinda Gates explains how he works like few others — “It’s chaos!” she exclaims.

After clips showing his drive and rise to massive success at Microsoft, portrayed as contrary to his mother’s best wishes, Gates says, “I had the wrong way of looking at things. In life you have to decide, ‘What’s important in the world?'”

The trailer then shifts into Gates’ work at the Bill and Melinda Gates Foundation and his focus after Microsoft on disease eradication, climate change and renewable energy. True to Gates’ own optimistic worldview, the music becomes more upbeat and the energy of the trailer rises again, showing what can be accomplished.

“There’s many challenges,” Gates says. “It’s harder than I expected.”

“Inside Bill’s Brain: Decoding Bill Gates” premieres on Netflix Sept. 20.
