In the first season, Lana and Clark Kent (Tom Welling) are just beginning their friendship, as she is a popular cheerleader dating star quarterback Whitney Fordman (Eric Johnson), and Clark cannot get near her without getting sick from the kryptonite necklace she wears.
As a result, Kreuk learns about the development of Lana as Lana is learning in the show, just as Welling does with Clark Kent.
By season three, Kreuk had decided to "invest" herself less in her character, as she felt that her character's ultimate development was entirely in the hands of the producers.
The character of Lana Lang, first created for comic books by Bill Finger and John Sikela in the 1950s as a romantic interest for Superboy, was adapted to television in 2001 by Alfred Gough and Miles Millar.
The character has also appeared in various literature based on the Smallville television series, none of which directly continues from or into the television episodes.
In the season eight episode "Bride", Oliver Queen (Justin Hartley), believing he is tracking Lex Luthor who has been missing since the season seven finale, discovers Lana instead.
