On the 2000s WB series Smallville, Erica Durance plays a young Lois Lane who came to Smallville to investigate the apparent death of her cousin, Chloe Sullivan. Durance plays a twenty year old Lois, despite the fact that she is five years older than Kate Bosworth, who plays an adult version of the character in the concurrently released Superman Returns. After teaming up with Clark Kent to find her cousin Chloe Sullivan, she returned for several guest star appearances in Season 4 before signing to return as a thirteen episode regular in Season 5. During this season, she dated Arthur Curry on episode "Aqua" before on the run from Lex's pursuit. This version of Lois was originally not interested in journalism at all, instead working in politics. In the sixth season Lois began to develop an interest in journalism, working at the tabloid paper, the Inquisitor. She began to investigate and write articles about the Green Arrow. Lois even enlisted Clarks and Jimmy's help in proving that Oliver Queen is actually the Green Arrow. She had been dating Oliver Queen, the Green Arrow, until they broke up in season 6 episode Justice. She also continues to work as the chief of staff for Martha Kent's senate seat. It has recently been announced that in the seventh season of Smallville, Lois will start to work for the Daily Planet as a reporter.
