Actor John Glover will reprise his role as Lex Luthor's father Lionel Luthor in the final season of Smallville, according to Ausiello Files.

Glover's Lionel Luthor was killed off in Season 7 of the show, but the site is reporting that Glover will appear in two episodes of the upcoming 10th Season that will premiere this fall, with his episodes said to air in November. Glover joins a growing list of Smallville alums that will return for the final season including John Schneider as Clark Kent's father, Laura Vandervoort as SuperGirl, James Marsters as Brainiac and Michael Shanks as Hawkman.

We spoke with series star Tom Welling at Comic-Con last month where he told us that Lex Luthor himself, Michael Rosenbaum, would also be returning for Season 10 as well.
