Primeval
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.
Primeval relied heavily on special effects which made it a costly show to produce. It was cancelled due to financial considerations after its third season, despite very high ratings. Following a public appeal, the production company Impossible Pictures partnered with ITV and their corporate competitor, UKTV, to finance a renewal.
The show returned with five webisodes in late 2010. Series four and five followed, featuring Potts and Spearritt and co-star Ben Miller with additional new cast members including Ben Mansfield and Ciarán McMenamin. During the break in filming, Potts and Spearritt underwent a physical transformation to conform with the plotline of the programme, which had matured their characters. "I'd played Connor for a few years and in a way he was always kind of the underdog and told what to do. In series four and five, though, he stepped up a bit and wanted to show and prove what he could do and what Cutter believed was in him from the start...I'm very grateful for what the writers gave me to do and I just hope that I did the material justice."
In 2012, Potts reprised the character of Connor in the Canadian spinoff, Primeval: New World as an "organic link between the original mythology and the new series universe". He appeared in 2 of the series' 13 episodes (first and last) which were filmed in Vancouver. The reboot starred Niall Matter as Evan Cross with Crystal Lowe as Toby Nance, the character corollary to Potts' Connor in the original. Despite the popularity of the original in North America, the new programme was cancelled after its initial run. In the finale several plot points were wrapped up, including an allusion that Connor and on-screen partner Abby Maitland married. Pott's acting in this episode was especially well received; "Andrew Lee Potts as Connor continues to light up this episode with a great mix of humour and pathos and really makes the piece."
