Bryan Cranston is moving on from chemistry to history. 

The 57-year-old star of AMC's recently-wrapped ratings monster "Breaking Bad," has been announced as the narrator behind the H2 network's new ambitious series "Big History." The 10-hour event will cover billions of years of history while attempting to present a unifying link among the world's greatest events. 

"I was asked to be The Voice of 13.7 billion years of history," said Cranston, "Sure, I've got the time - give or take a billion years. As I read the material I realized that this new series gives a surprising and unique look at our world. I'm excited to be a part of it."

According to the release, each episode of "Big History" will begin with an iconic topic from the pages of traditional history such as the Great Pyramids, The Titanic or the American Revolution but then will spin into surprising journeys through other fields, weaving together insights and evidence from various disciplines such as astronomy, physics, chemistry, biology, anthropology, history and economics. 

The inspiration for the series comes from a popular course of the same name taught by historian and professor David Christian. After taking the course himself, Microsoft co-founder and philanthropist Bill Gates joined forces with Christian to create a free online suitable for middle and high schools. That course will launch at the end of October just before the television series premieres. 

"Big History is my favorite course of all time," says Gates, "Big History literally tells the story of the universe from the very beginning to the complex societies we have today. It shows how everything is connected to everything else. It weaves together insights and evidence from so many disciplines into a single, understandable story."

While no trailer yet exists for the H2 series, you can get an idea of the approach it will take by watching one for the Big History Project below. The series debuts Saturday, November 2 at 10PM ET.
