Scottish actor Angus Macfadyen will appear in The CW's Superman & Lois, playing the role of Jor-El, ComicBook.com has learned exclusively. The character is going to serve much the same role in Superman & Lois that he has done in previous installments of the Superman mythology: he will serve as a spectral guide to his son, Superman, via the technology of the Fortress of Solitude.
Official character description
"Jor-El is Clark Kent's Kryptonian father. Though he died along with Krypton, his brilliant essence still exists within the arctic Fortress of Solitude to provide guidance when his son seeks help."
