Oliver Valentine

Oliver "Ollie" Valentine is a fictional character from the BBC medical drama Holby City, played by actor James Anderson. He first appeared in the eleventh series episode "Proceed With Caution", broadcast on 9 June 2009. Oliver was introduced alongside his older sister, Penny (Emma Catherwood), as a Foundation House Officer 1 (F1) on rotation at Holby City Hospital. Series producer Diana Kyle intended their inclusion to have an "instant impact on the wards." Anderson was selected to play Oliver; he spent time with a real F1 doctor and trained with the programme's medical advisors to prepare for the part. It took him around six months to ease into the role, and a further six to feel comfortable in it.

Oliver was initially portrayed as "the golden boy" compared to his sister. Boyishly charming and medically talented, he nonetheless lacked confidence in his ability. When Oliver reached his F2 training, the series formed an on-screen duo by pairing him with registrar Greg Douglas (Edward MacLiam). Oliver's lack of competency was highlighted – he endangered patients and landed his colleagues in trouble. In a prominent storyline, Oliver made a series of medical errors, which forced him to admit that he cheated on an exam at medical school. He began a downward spiral, and reached "rock bottom" when Penny was killed off. He was then central to a special flashback episode, which depicted his battle to cope with her death. Though he confessed to Director of Surgery Henrik Hanssen (Guy Henry) that he was not truly qualified, Hanssen allowed Oliver to continue practising medicine.
