Tapping’s Carter will be in 14 episodes in Season Four

Amanda Tapping has posted on her official website about her move to Stargate Atlantis for the show’s fourth season. She also talked about her work schedule and the SG-1 movies:
I am also joining the cast of Atlantis next year for 14 episodes!! I am delighted. I have been quoted as saying that “I am contractually obligated to the franchise for another year.” This sounds incredibly cold. It’s strange sometimes to see your words in print. I want to be on the record as saying that I am very excited about the move to Atlantis. I think it’s a wonderful opportunity for the character of Carter and for me personally. I am also aware that some people are not thrilled with the idea. I can only say that I think it will be a nice fit. I know Atlantis is not my show and I intend to tread lightly on their boards. I have a huge amount of respect for the cast and crew and hope that I will add to the show and not take away from anyone. I have talked at great length with Joe and Paul. When they first pitched the idea to me, I was a little nervous. After talking to them I am convinced that this is a good move. They are very excited about show running Atlantis and I am sure their enthusiasm will be felt on screen. I will also be in the two SG-1 TV movies which are shooting in April and June. I am looking at a very busy and fulfilling year. Surprisingly, I will have a bit more time off this year to spend with my family as I am only scheduled for four days per episode on Atlantis. This is perfect for me. Olivia is an absolute wonder and Alan and I are enjoying this time immensely.
