Donald Sutherland credited as playing...
Dr. Sid
- Doctor Sid: Remember what happened to Galileo? They threw him in jail because he said the earth was not the center of the universe. That could happen to us.
- Doctor Sid: Oh, and stay away from your friend the Captain. You save his life, he saves yours, one thing leads to another... I was young once too.
- Doctor Aki Ross: Doctor, there's a war going on. Nobody's young anymore.
- [before driving through the windows to the landing bay]
- Doctor Sid: So I gather this will be somewhat of a rough ride.
- Neil: Doc, you got a talent for understatement.
- [after the vehicle crashes dislocating two tires and losing one]
- Doctor Sid: Interesting.
- Aki: All life is born of Gaia and each life has a spirit. Each new spirit is housed in a physical body. Doctor?
- Doctor Sid: Go on.
- Aki: Through their experiences on Earth, each spirit matures and grows. When the physical body dies, the mature spirit, enriched by its life on Earth, returns to Gaia, bringing with it the experiences, enabling Gaia to live and grow.
