Fast forward the movie to where Kane has been lowered into the canyon and he slips into the mist where the eggs are. When he goes to see the egg that has "Organic Life," you can see the egg sweating. Instead of rolling down, the egg is rolling up. The egg is shooting off and up towards the ceiling, indicating that the egg was filmed upside down.
Actually they did that on purpose - if you have the DVD, Ridley Scott (the director) says that they deliberately shot it upside down, to deliberatelyhave it sweat up to have a certain "supernatural" aura or something
What are you talking about? You mean the 'sweat' is dripping upwards instead of down? So what! It's an alien spacecraft and an alien egg. It looks cool and it's not a slip up.
Just as cork floats in water because it is less dense, isn't it possible, however unlikely, that a liquid could exist that is less dense than a gas? Quite an eerie effect.
This is true. It was done on purpose. I have the Alien Quadrilogy and in the commentary it states that they wanted a really Alien looking effect so they filmed it upside down to make the goo move backwards.
