David Nykl: (On the possibility of cancellation of Stargate Atlantis) Yeah, it is similar in that an actor's daily bread is uncertainty. Really, we have to remember that we're in the lucky minority, us Stargate people, to be working as regularly. Even the four seasons that have been around so far. Now, of course, we're all optimistic and looking forward to a Season Five, but there are no promises. There are no guarantees. We carry on and there are contingency plans, and plans B's and C's and D's. I'm speaking for myself of course, in my head, but I think other actors have a similar trepidation. "What will happen if we don't go back?"
