Jacob Masters
On 13 February 2015, the BBC Media Centre announced Charles Venn had joined the cast of "Casualty" as new nurse Jacob Masters. Venn began filming at the show's Roath Lock Studios that same week. Of his casting, Venn commented, "It's truly a pleasure and honour to be part of "Casualty" as it's such a successful long-standing medical drama. I'm keenly relishing the challenge and my time in Cardiff and I look forward to tackling the role of nurse Jacob." Shorty after he was cast as Jacob, Venn's mother told him that he would be working alongside his cousin, Azuka Oforka (who plays Louise Tyler). Venn admitted that he had no idea they were related, but called it a "wonderful surprise" and said they had worked on a storyline together. Venn filmed five months worth of scenes before they aired. He made his first appearance as Jacob during the episode broadcast on 18 July 2015.
