Smallville

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.

Although he plays the lead character, Tom Welling has admitted in interviews that he is not a fan of the Superman comic books. However, Welling believed his lack of knowledge on the character mythology actually helped his portrayal of Clark.

Lex Luthor's mansion is the same mansion used in 'X-Men 2' as well as CW's 'Arrow'.
