Thor: The Dark World star Jamie Alexander will return as Lady Sif in the March 11 episode of Marvel's Agents of S.H.I.E.L.D. entitled Yes Man, and we have your first look courtesy of TV Guide, followed by new details from producers Jed Whedon and Maurissa Tancharoen.
In /tv/marvels-agents-of-s-h-i-e-l-d/Yes Man, the Agents of S.H.I.E.L.D. have met their match when attacked by the deadly Lorelei (Elena Satine) from Marvel's Thor comic books. Jamie Alexander will reprise her role as Lady Sif, who arrives to save the S.H.E.I.L.D. team on March 11.
About the character's return, Jed Whedon stated,
"We always have our radar up for ways to tie our series into the Marvel films and bringing in an Asgardian really cements that connection. Lady Sif comes here on a hunting mission, sent by Odin, to find her archenemy Lorelei and bring her back to Asgard. It throws our agents for a loop when they find themselves in a fight right alongside this powerful woman from Thor's world."
"Jamie walked onto the set in full Lady Sif regalia just as she looks in the movies, from the huge, mile-high boots to the metal armor, and she towered over everyone. It was so striking and impressive, all we could do was stare. It was very cool!"
