After 'Star Trek,' I was the commander on 'Stargate Atlantis,' the final season, and once my character had become a good commander, I was sorry that the show didn't last beyond that.

I didn't realize it at first, but the Doctor is in the same spirit as those natural 'outsider' characters 'Star Trek' series have, like Spock and Data.

As you know, when Star Trek was canceled after the second season, it was the activism of the fans that revived it for a third season.

If you're looking at my other major science fiction roles - the Doctor on 'Star Trek' and certainly Woolsey on 'Stargate' - I often play characters that might be good theorists and good thinkers, but you wouldn't call either of them very macho characters.

I grew up with 'Star Wars,' not 'Star Trek.'
