Meet the cast of Showtrial, BBC One's new legal drama

It will be up to solicitor Cleo Roberts (Tracy Ifeachor) to back her up, with court proceedings looming and increasing pressure from Talitha's powerful property developer father, Damian (James Frain).

If you found yourself reeling from the first instalment, our Showtrial episode one questions offer some ideas on the storylines to look out for ahead of tonight's episode.

Alternatively, if you're yet to tune in, our Showtrial review is here to help you decide whether the show is worth your time, with it being something of a mixed bag thus far.

Read on for your complete guide to the Showtrial cast and characters – including where you might have seen them before.

Tracy Ifeachor plays Cleo Roberts

Who is Cleo Roberts? Cleo is the duty solicitor on call the night that Talitha is arrested and decides to take on the case despite mounting odds. She doesn't take any nonsense from her spoilt client and has a sharp strategic mind that might just be enough to prepare a solid defence – whether her client is innocent or not. Cleo has so far resisted attempts at intimidation from Talitha's father, who wants information and control over his daughter's case.

"To see a character who looks like Cleo lead a show was phenomenal and I couldn't believe it. And I'm so grateful to World Productions for writing such an amazing piece for someone like me to play and be a part of," said Ifeachor, in an interview with RadioTimes.com and other press.

"I hope that the next generation of children who look like me are able to see this and be proud... and really see themselves in a positive light and maybe even think, 'Hey, why don't I become a lawyer? Why don't I become a barrister? Why don't I become a solicitor advocate? I see them doing it, that looks like fun.'"

What else has Tracy Ifeachor been in? Ifeachor has bagged supporting roles in several US dramas, including The Originals, Quantico, DC's Legends of Tomorrow and Jason Bourne spin-off Treadstone. Previously, she had also appeared in David Tennant's two-part Doctor Who swansong The End of Time.

Celine Buckens plays Talitha Campbell

Who is Talitha Campbell? Talitha is a university student and the spoilt daughter of a wealthy property developer. She is considered a suspect in the murder of fellow pupil Hannah, as they had exchanged threatening text messages in the days leading up to her disappearance at the end-of-year ball. She has an abrasive and arrogant demeanour that Cleo fears will not go down well with a jury.

Buckens teased that Showtrial will "subvert" our expectations for this kind of character, telling RadioTimes.com and other press: "You think you've got a clear cut situation, but actually you don't. Talitha comes from a really wealthy family, but also has an estranged relationship with her father and has supported herself through some sex work, so it's not clear-cut."

What else has Celine Buckens been in? Buckens got her breakout role in 2011 in the cast of Steven Spielberg's film adaptation of War Horse. She went on to secure recurring roles in Netflix original series Free Rein and US drama Warrior, based on an original concept by martial arts legend Bruce Lee.

Sinéad Keenan plays DI Paula Cassidy

Who is DI Paula Cassidy? Cassidy is the lead detective investigating Hannah's disappearance, who takes an instant disliking to Talitha. She believes that the privileged teen knows more than she is letting on and is keen to see her behind bars, but she'll need sturdy evidence to convince the Crown Prosecution Service to move forward.

What else has Sinéad Keenan been in? Keenan previously worked with Showtrial co-star Tracy Ifeachor on Doctor Who two-parter The End of Time. Since then, she has gone on to major roles in Being Human and Little Boy Blue, the latter of which earned her a BAFTA TV Award nomination for Best Actress. Most recently, she appeared in BBC One's hard-hitting drama Three Families, which aired across two nights in May 2021.
