Robert Carlyle is a fine actor with an impressive resume (The Full Monty, 28 Weeks Later, 24: Redemption to name a few), but he'll always be the hard-drinking, C-word screaming, Ewan McGregor-slapping Begbie from Trainspotting to me. Which is why it comes as a surprise that he's been cast as the lead in the next Stargate series, Stargate Universe.

Carlyle will play Dr. David Rush, leader of a group of scientists and civilians trapped on a ship traveling through space. Word is that Dr. Rush, charged with finding a way to return his crew home, might not be the nice guy everyone thinks he is.

There has been quite a bit of speculation about the move, but now it's official. Amanda Tapping will be joining the cast of Stargate: Atlantis for 14 episodes in season four. Executive Producer Brad Wright said that the idea is one that they have been considering for a long time, but they held back because SG-1 kept going. The recent announcement that SG-1 won't be returning after the current season has opened the door for Colonel Carter to make the jump.

Season four of Atlantis marks another change for the show. As Wright and fellow Executive Producer Robert C. Cooper turn their attention to the SG-1 movies, Joseph Mallozzi and Paul Mullie will take over as show-runners for Atlantis.I like the addition of Tapping to the cast. I've always been a fan of Carter, and with Paul McGillion not returning as Dr. Becket in season four, there is an opening to be filled.
