 Allison Mack toyed with the idea of auditioning for the role of Lana Lang but chose instead to audition for the role of Chloe Sullivan.The character was created just for the series and was intended to add ethnic diversity to the cast, but part of the reason Gough and Millar chose to cast Mack, against their initial intentions to give the character an ethnic background, was because they were impressed with Allison Mack's "rare ability to deliver large chunks of expositionary dialogue conversationally".Sam Jones III, who plays Pete Ross, was the last of the series regulars to be cast.
