Teri Hatcher will be guest starring on Supergirl.

Supergirl has landed a real and spectacular guest star to play this year’s Big Bad.

Teri Hatcher played Lois Lane on the now-classic Lois & Clark: The New Adventures of Superman, and it has been announced this morning that the actress will be joining the cast of Supergirl this Winter for a multi-episode arc.

Details are sparse about this mysterious new role but she’s been described as someone who “will become the new Big Bad of Season 2.”

Since playing Lois Lane, Teri had an even bigger role in the past decade in Desperate Housewives. More recently, she appeared in the most recent season of The Odd Couple on CBS. She also appeared in a final season episode of Smallville as the mother of Erica Durance’s Lois Lane, fitting as 1950s Lois Phyllis Coates once appeared on Lois & Clark as her mother.

“No offense to any of the wonderful actresses who have also played the part, but Teri Hatcher is my all time favorite Lois Lane. To have her come back to the SuperWorld in a completely different part is an unbelievable gift to me, Greg, and the fans,” Supergirl Executive Producer Andrew Kreisberg said in a statement.

Interesting connection to note: On Desperate Housewives, Teri got to work with Mehcad Brooks (James). We asked Mehcad about that connection in an interview before the show premiered.

Teri’s casting brings up two big questions for us. One, will she have a scene with Dean Cain (please?), because that would make us feel warm and fuzzy like the few seconds of The Flash last year that reunited John Wesley Shipp and Amanda Pays before… well, we don’t go there. The other: Can Calista Flockhart fly back up as Cat so we can have that Lois Lane vs. Ally McBeal cat fight that we’ve wanted for twenty years?

Either way, no confirmed word on when Teri’s episodes will air, so stay tuned and we will share that information when it becomes available. Still very cool. Teri joins Dean Cain, Helen Slater, and Laura Vandervoort in the list of actors from the Super-franchise that have appeared in Supergirl so far. That’s the fun thing about starring in a Super-project: Even years after the fact, you always come back in a new role, eventually.
