10. Jensen Ackles, who plays Jason Teague in season 4, was the second choice to play Clark Kent. If Tom Welling had not accepted the part, the role would have gone to him.

11. After the fifth season, the show was picked up by The CW because The WB merged with UPN to form The CW.

23. The episode “Fallout” 6.06 was one of the highest rated episodes of Smallville’s sixth season. 4

24. The costume Tom Welling dons as Green Arrow in the episode “Hydro” 6.10 is not actually the one worn by Justin Hartley. Hartley explains why: 

“It’s a little embarrassing, but Tom could not even fit in my costume,” he confesses, sheepishly. “I thought, this is cool man. I’ve been working out. I’m looking pretty good, but then Tom has to wear the costume, and he’s huge. He’s just a big dude, and he’s got a lot more muscle than I do. In the end, he had to wear the stunt guy’s outfit, which is basically my outfit but bigger because it’s made to put pads under it – so it’s actually a lot bigger. I was like, “You jerk. I’m going to look like the size medium!” 4

25. In several drafts of the “Veritas” 7.15 script, Clark was briefly able to fly after Kara and Brainiac; this scene was cut before filming, due to budgetary constraints. 3

31. In “Metamorphosis” 1.02, it’s actually strips of ham that meteor-infected bug-man, Greg Arkin (Chad E. Donella) is peeling off himself. According to the producers, the ladies on the writing staff couldn’t watch the scene because it was too disgusting. 6

32. During filming of “Shattered” 3.08, Michael Rosenbaum caught someone trying to steal his van, and channeled his real-life frustration into his performance in his final scene with John Glover (Lionel Luthor). 7

34. In the episode “Obsession” 3.14, then executive producer Al Gough revealed “It’s one of the few times where you bring in the guest star of the week to be the love interest and you really believe it,” he notes. “Tom Welling and Sarah Carter (Alicia Baker) had real chemistry. We tried to do it with Kyra, the wolf girl in season two’s ‘Skinwalker’, but you didn’t quite believe it. With this character you did.” Which is why the producers brought Sarah Carter back for season four. 7

35. Fans began requesting Alicia Baker’s return within minutes of the conclusion of season three’s “Obsession” episode. 8

36. In the episode “Covenant” 3.22 when Lionel Luthor is sitting in a prison chair and his locks are being shorn, that was John Glover’s idea. He was doing a play in Philadelphia for the summer and needed to cut his hair and said, “What if we did it in a prison on the show?” Glover made his proposal during the filming of “Memoria” 3.19 to Miles Millar in the makeup trailer and Miles was very happy with the idea. 7

37. In the episode “Phoenix” 3.02, Tom Welling and John Schneider did a ton of the stunts themselves in the beginning of the episode’s fight scene with the two Kents. “We did more than we probably should have,” Tom Welling laughs. “Obviously we didn’t do the stunts with the big impact, but we came up with quite a lot of ideas while we were doing it. They wanted to show our faces doing it, so whenever you see it’s us, it really is us.” 7

38. In the episode “Run” 4.04 when Clark goes to Bart Allen’s (Impulse) hotel room and finds Bart’s fake ID cards for Barry Allen, Jay Garrick and Wally West, all three names represent some of DC Comics’ most famous alter-egos of the Flash. 8
