Stargate Atlantis executive producer and co-showrunner Joseph Mallozzi has been asked in his personal blog several times whether or not Dr. Daniel Jackson (Michael Shanks) will visit Atlantis in Season Four.
Here’s his latest reply, posted August 8, 2007:
Alas, in response to many who have been asking, Daniel Jackson will not be making an appearance in season four (although Michael was on the lot today to do an interview for one of Ivon Bartok’s upcoming DVD Special Features). But, if we get a fifth season pick-up, it’s definitely something we definitely aim to pursue.
Ben Browder and Claudia Black are also not appearing in Season Four, but viewers can expect to see Amanda Tapping (as a new, regular cast member in 14 episodes) and Christopher Judge (guest starring in at least one episode: “Reunion”).
I don’t mind characters coming over from SG-1… but I appreciate that they’re taking it slow. It wouldn’t be realistic if everyone suddenly popped up in SGA. Good call, PTB! 😀
