Smallville

Chloe and Whitney were created specifically for the show (they were never mentioned in the Superman comics). However, in 2003, DC Comics announced that Chloe would be introduced into the Superman comics.

Annette O'Toole (Martha Kent) previously played Lana Lang in 'Superman III'.

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.
