The best part of "Aliens of the Deep" is watching how gee-whiz excited you get down there. Yeah--how I get, how the scientists get. I love taking these Ph.D.s out there and watching them reduced to 5-year-old kids. Are they easier to work with than, say, actors? [ Laughs ] Well, it's funny, there's some of the same concerns: How do I look? Am I doing something stupid? The thing is, science is important to every scientist. But maybe one in 10 can express why.
