It's A Bird! It's A Plane! It's ... A Dog Dangling From A Helicopter?!

A new IMAX movie opens with a rescue worker named Henry dangling from a helicopter, working to save a skier trapped in an avalanche.

Henry wears a vest and goggles and, oh, by the way, is a border collie.

"Henry is like the real-life James Bond of dogs," says Daniel Ferguson, director of Superpower Dogs.

The film follows six remarkable dogs who work in fields such as avalanche and water rescue, endangered species protection, and emotional support.

"I think casting makes a movie, and in this case it's no exception," Ferguson says. "The dogs are at the heart of this film."

Ferguson tells NPR about how a producer talked him into making a movie about dogs (even though he's more of a cat person) and how he attempted to re-create a dog's visual perspective on an IMAX screen.
