Former “Stargate: SG1” regular Michael Shanks reports he’s been invited to come aboard “Stargate: Atlantis.” “It was the most cryptic, enigmatic pitch of a story I’ve ever heard,” say Shanks, who’ll be reprising his popular “SG1” role as Dr. Daniel Jackson in a recurring capacity. “The pitch was: ‘You go to Atlantis and something happens and Daniel has to help everybody to get rid of the bad guys that are coming.’ I was like, ‘Wow, did you spend a lot of time thinking that one up?’ But it’s one of those things. Stargate is like old home. It’s always nice to be able to revisit that universe and those individuals and to play that character again.”
