Smallville Cast: Where Are They Now?
3. John Glover
The intimidating father of Lex Luthor that somehow found himself on a redemptive path, Lionel Luthor was a larger-than-life personality brought to life with ease by the veteran that is John Glover.
Having already amassed a legendary career before his seven-year Smallville stint, Glover began to wind his on-screen career down after his time on the show (as a regular) came to an end. However, he has returned to Broadway a number of times, starring in productions such as Death of A Salesman, Macbeth and Saint Joan.
He has played supporting roles in a few films and also made occasional guest appearances on TV since, but his most well-known recent offering came in another DC Comics property when he played played Mr. Sivana in 2019's Shazam.
