I can only find listings for the usual gang of five, but in the two episodes we've seen there's the doctor and few of Teyla's people who deserve recognition -- like at least a name and a bio somewhere.
Warning - Useless Trivia Ahead
Another entry into the "Deja Vu...all over again" category.
I thought Christopher Heyerdahl "Halling" looked familiar and I eventually remembered him as being Pallin from SG1 Season 7 Revisions.
However, I was slow to the draw on Paul McGillion "Carson Beckett M.D." I knew I liked him but he didn't seem familiar. I so missed it. He was the young Ernest Littlefield in SG1 Torment of Tantalus. http://imdb.com/name/nm0569295/
How ironic that his characters have preceeded and succeeded SG1 in going through the gate.
I've been requested to open new forums for particular members of the Atlantis team, but the number of posts in this section at present just doesn't warrant that. I'm happy to do that if people want to post biographies and pose questions about the cast.
The only one I've done it for now is Elizabeth Weir, since her recasting has generated quite a bit of discussion already.
