(l-r) Captain Becker, Jess Parker, Matt Anderson, Abby Maitland and Connor Temple
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.
Stephen Hart and Oliver Leek are killed off in the final episode of Series 2, and Caroline Steel leaves. Series 3 sees the introduction of Laila Rouass as Sarah Page, Ben Mansfield as Captain Becker and Jason Flemyng as Danny Quinn. In the third episode Nick Cutter is killed, with Danny Quinn replacing him as team leader. Jenny Lewis leaves two episodes later (returning for the penultimate episode of Series 4); and in the finale of Series 3, Helen Cutter is knocked off a cliff by a Raptor.
Sarah Page was killed offscreen prior to Series 4, and Danny Quinn returned only in the finale of Series 4. Joining the cast was Ciarán McMenamin as Matt Anderson, the new team leader, Ruth Kearney as Jess Parker, team coordinator, Alexander Siddig as Philip Burton, an industrialist who is put in charge of the ARC, Anton Lesser as Gideon, Ruth Bradley as Emily Merchant and Jonathyn Byrne as Ethan Dobrowski.
The Series 4 line-up returned for Series 5 with the exception of Gideon and Ethan Dobrowski. They were joined by Janice Byrne as April Leonard, Philip Burton's assistant. At the end of Series 5, the only original cast members remaining were Andrew-Lee Potts, Hannah Spearritt and Ben Miller.
