Greg Marshall | Producer
It was a shark, 14 years ago in Belize, that inspired Greg’s invention of the Crittercam animal-mounted video camera he used to make Tiger Shark and other films. “Of all shark species,” said Greg, “tiger sharks are probably the most dangerous to humans.” His main goal for Tiger Shark: transform the audience’s fear into awe.
Birgit Buhleier | Co-producer
“I’m mostly interested in good science,” said Birgit, who holds a master’s degree in pharmaceutical chemistry and is the team’s technology coordinator. Birgit has only just learned to appreciate sharks. “In fact, learning to love sharks is one of the goals of the film—and it’s working!”
John Bredar | Field Producer
John was brought in to translate scientist Mike Heithaus’s ideas into common English and to direct the topside sequences, with Greg Marshall directing the underwater crew. “John is the best at evoking good conversation on camera,” Greg says. And it didn’t hurt that John was already in the neighborhood—Australia—working on EXPLORER’s Great White, Deep Trouble (look for it April 9, 2000, at 8 p.m. ET/PT on CNBC).
Mike Heithaus | Scientist
Mike, a Ph.D. candidate and National Geographic Expeditions Council grantee, is studying the Shark Bay ecosystem. The shoot was a way for him to find out what tiger sharks eat without killing them—an impossible task, according to a fellow student. Crittercam made it possible, and Mike’s project marks the technology’s burgeoning research and academic use.
Mark Holmes | Online Correspondent
As vice president of programming and content development at nationalgeographic.com, I’m more accustomed to bytes than bites. I am, however, familiar with sharks and have done some shark tagging off the coast of my native New England. I thought I’d seen everything, until I encountered scientist Mike Heithaus’s swashbuckling style of research on the Tiger Shark shoot.
