The Big Picture
- Michael Rosenbaum's version of Lex Luthor in Smallville evolved into the classic comic book villain, largely influenced by his father Lionel, played by John Glover.
- In Season 7, Glover suggested to the writers that Lex should kill Lionel, sealing his fate as a villain.
- Despite Lionel's death in Season 7, Glover returned to the series as an alternate version of the character in Season 10, and the character had a significant role in the series finale.
