While we will be going individually into some of these cast members and their portrayal of their characters, this is more focused on the cast as a whole. Smallville was Clark Kent’s story, but the supporting characters around him, had just as much of a focus as he did.

The cast would also evolve throughout the ten years, with former cast members leaving and new ones arriving, like Cassidy Freeman’s Tess Mercer and Justin Hartley’s Oliver Queen.
