Patricia Potter

On stage, Potter has appeared in theatrical versions of The Duchess of Malfi, Much Ado About Nothing, and Happy End. Her first television role came in 1997, when she played a florist in the third series of ITV drama Soldier Soldier. Potter has also appeared in The Bill, Brookside and the Scarlet Pimpernel, as well as the film Shakespeare in Love. She played herself in Ricky Gervais's comedy Extras as an ex-girlfriend of Gervais' character Andy Millman. She said of the role: "It was quite frightening leaving the security of the Holby environment which I know so well and going onto a new set but it was a fantastic experience which I thoroughly enjoyed."

Potter's most notable role to date was that of Diane Lloyd in BBC medical drama series Holby City. While researching for the Casualty spin off, she witnessed open heart surgery to enhance her role as a medical employee, deeming the experience "fascinating", and stating: "I think I'd have made a good surgeon in real life as I'm very careful and fussy about making my stitches perfect!" On her favourite storyline in the show, she has explained: "Although it was terribly sad, I really enjoyed Steve's departure from the show – the added trauma of the abortion and Diane's relationship with Steve meant that Diane showed some vulnerability – she's usually very strong – and I enjoyed having a good cry. It was also great to be involved in Alex's Parkinson storyline." Of her former cast members, Potter has said: "Everyone is fun to work with here – we're all really lucky to be amongst such lovely people. I work most regularly with Hugh Quarshie who is brilliant so I'm extra lucky." In October 2006, Potter announced her intention to leave the show after four years. "I have really enjoyed and am still enjoying my time on Holby, I've had some fantastic storylines, but after 4 years on the show I felt it was time to move on to other projects. I wanted to move before I became too complacent. You have to weigh up if it's worth leaving a job that you really enjoy to face the unknown".

After leaving Holby City, Potter appeared in BBC One sitcom Jam and Jerusalem, before returning to theatre with the play An Eligible Man. She said of the transition: "I'm in a strange state somewhere between excitement and terror! It's been a long time since I was last on stage so I was worried that I would find it difficult and frightening but actually it's been great fun and I've thoroughly enjoyed the rehearsal process. We had our first preview last night which was quite an adrenaline rush!" Then from 2016 to 2017, she appeared in the BBC soap opera Doctors as Jane Fairweather. In 2023 she appeared as Oonagh Wallace in Vera (S12, Ep 1)
