I remember seeing a deep-sea special about tubeworms that live near these deep-sea vents. They were in this little sub thing that was specially built to withstand tremendous amounts of pressure, with windows that were like 6 inches thick and the structure was reinforced in like 5 different ways and all this stuff. The guy piloting the thing was all "ok, we're going to get closer to the vents, but not too close, because if we get within X feet from the vent, our windows will melt and our sub will go from having 20 square feet of space to 2 in about half a second" and I was like "I will never ever do that ever".

James Cameron is braver than I. Space and deep sea exploration would scare the shit out of me. If I ever found myself suddenly in a deep sea sub or on a space station, I would probably spend a couple hours just pissing myself and vomiting before I had the nerve to look out the window.

Are you using the right version? I believe this is the directors edition they are using.

so I played forward a bit in the movie and the part that it's supposed to sync up with is about 3 minutes later.  It's when Lindsey is developing film and Bud takes the black curtain off the port hole.  The Garfield Suction toy is right there.
