While superheroes may be all the rage right now with endless films and series, The WB/The CW were ahead of the curve with the Superman origin series, Smallville. During Smallville’s 10 season-run from 2001-2011, there were a lot of guest stars, and some were very recognizable including Superman legends like Christopher Reeve, Dean Cain and more, but looking back on the series there were quite a few more well-known faces in the cast. Check out these 12 celebrities you forgot appeared/guest starred in Smallville:
12. Jonathan Taylor Thomas
Past his time as Randy Taylor on Home Improvement, not much has been seen of Jonathan Taylor Thomas. While many assumed he had quit acting altogether, he did make a few special appearances in series such as Veronica Mars, 8 Simple Rules, and Smallville. Jonathan Taylor Thomas appeared on the superhero series twice as Ian Randall and made his first cameo in the season two episode “Dichotic.” Thomas, like so many other celebrity guest stars, played a metahuman transformed by the meteor rocks, who became one of Clark’s enemies. Ian Randall was exceptionally intelligent and his powers gave him the ability to duplicate himself. After being banished to Belle Reve, Randall returned in season 3’s “Asylum” but was defeated once and for all at the end of the episode.
