Actor John Shea also had the role on TV during the reign of Lois & Cark from 1993-1997, with Clancy Brown doing voice over duties for a popular string of DC animated projects as Lex during the early to late 2000s.
Much more recently, the big screen gave us Jesse Eisenberg as a not-yet-bald version of the character in 2016’s Batman v Superman: Dawn of Justice.
The character of Lex Luthor hasn’t been seen in live action on the small screen since the above-mentioned Michael Rosenbaum left his role on Smallville way back in 2008 (this doesn’t include his appearance in the 2011 finale, of course).
