List of Primeval characters

This is a list of characters in the ITV science fiction television series Primeval, including supporting characters.

The series originally features a cast of five main characters plus supporting cast who investigate time anomalies for the British government. The series 1 cast is made up of Douglas Henshall as Professor Nick Cutter, James Murray as Stephen Hart, Andrew-Lee Potts as Connor Temple, Lucy Brown as Claudia Brown and Hannah Spearritt as Abby Maitland, with Juliet Aubrey as Helen Cutter, Ben Miller as James Lester and Mark Wakeling as Captain Tom Ryan.

In the final episode of Series 1, Captain Tom Ryan is killed off, and Claudia Brown disappears. The rest of the cast carries over into Series 2. Lucy Brown plays a new character, Jenny Lewis, a savvy PR person and a doppelgänger of Claudia, but unlike her, she has no romantic attachment to Cutter and resents him referring to her as "Claudia". Karl Theobald as Oliver Leek, Naomi Bentley as Caroline Steel and Tim Faraday as "The Cleaner" support.
