In 2007, Potts originated the role of Connor Temple in the science fiction programme, "Primeval". Although critically panned as campy on its debut, it became a hit show and pop cultural phenomenon. The storyline saw a team of scientists battling prehistoric and future beasts falling into the present through anomalies in time. Potts played geeky antihero Connor Temple, the vulnerable and innocent student of lead Nick Cutter (Douglas Henshall). "Connor just came really easy to me. It was something organic that I discovered quite naturally with the character and everyone on "Primeval" allowed me to run with that." During the course of programme, Potts became romantically coupled with co-star Hannah Spearritt both on-screen and off-screen, which garnered media attention for both the couple and the show.
