This week Smallville is getting a very big guest star: Teri Hatcher. The current Desperate Housewives star famously played Lois Lane on the '90s TV series Lois and Clark: The Adventures of Superman, and now she's taking on the role of Lois Lane's mom.

If you're wondering how Hatcher (age 45) can play the mother of Erica Durance (age 32), it's because she'll be appearing in old video tapes recorded before Lois' mom, Ella, died. Check out this Hatcher-centric promo.



There's also a clip from the episode, "Abandoned," featuring Lois Lane going through her mother's old things.



This episode of Smallville isn't just about Lois Lane's past. Tess Mercer's childhood will also be revealed as she returns to her old orphanage run by Granny Goodness. The episode also features another special guest star: Lindsay Hartley, Justin Hartley's wife.



Smallville airs Friday at 8pm on the CW.
