(Kevin) Rafferty spends most of his time these days at the Submarine lagoon, getting ready to open a new attraction next year. The old subs closed in 1998. He talked about how the ride developed, and how he became an Imagineer.

Q: What are some of the challenges in telling a story that's under water?

A: Our first instinct is to create a linear story. But on a 32-foot submarine, with a series of individual scenes and characters, the people at the front end of the sub will not see the same thing (passing through) as those at the end. In my 28 years, this has been the biggest story challenge for us to figure out. The guest in the front of the sub will get a different audio and visual portion than someone at the end, but it will all be equal show value and they'll all get the gist of that scene and the meat of the story. ... The exciting part is that we'll have it all done and tested in a virtual world before we put it in the subs.

Q. There are separate portholes in the subs to see the story, but how will people hear different audio tracks?

A. We're developing audio with new fidelity that you've never heard before and a killer sub woofer (he can't resist that line).
