The Kickstarter campaign for a film about science educator Bill Nye has become the most-funded documentary in the site’s history with more than $680,000 pledged from nearly 14,000 backers.

The campaign launched July 13 with a goal of $650,000 and will conclude Aug. 13.

The previous Kickstarter record-holder for a documentary was “For the Love of Spock,” produced by Adam Nimoy about his father Leonard Nimoy, which received $662,400 in pledges.

The film about Nye, best known as “the Science Guy,” is directed by David Alvarado and Jason Sussberg, who teamed on the documentary “The Immortalists.” Seth Gordon and Nick Pampenella are producing. Gordon won the Academy Award for best documentary for “Undefeated.”

Nye is CEO of the Planetary Society, where he’s leading a mission to launch a solar-powered satellite into the cosmos and advocating for the importance of science, technology and discovery.

Donation incentives include a sneak peek of the film, in which Nye witnesses the launch of his solar sail into space, his handwritten notes from the evolution vs. creationism debate, one of his bowties and an associate producer credit for $10,000 — with four of the seven credits receiving pledges.

Nye appeared in the live-action educational segments of “Back to the Future: The Animated Series,” in which he would demonstrate science while Christopher Lloyd explained. He hosted 100 episodes of “Bill Nye the Science Guy” from 1993 to 1998 for Disney/PBS. The show targeted children but attracted a wide adult audience as well.
