I actually DO remember this Pavilion but when I was first at Disney World back in 1973, when I was just 13, we didn't have EPCOT opened yet, and when I went back in the mid-80's, I thought that the movie they showed was a rip off the Fantastic Voyage sci-fi movie with riders traveling along the blood flow. Oh, and your brain is inside your CRAIN-E-UM, or skull.
