Meet the cast of The Pembrokeshire Murders

Hollywood star Luke Evans plays the lead role of Wilkins and a number of recognisable faces in supporting roles.

The cast is predominately Welsh, with executive producer Simon Heath having explained to RadioTimes.com that this was vital in ensuring the authenticity of the series.

"I like actors to be from the area they're portraying," he explained. "I like people in their own accents if at all possible and I think we had a brilliant casting director who found a fantastic Welsh cast for us."

Meanwhile, although most of the characters are directly based on real people, others are amalgamations of various different people, and some names have been changed for the programme.

Read on for everything you need to know about the cast, including which real-life figures they are playing and where you might have seen them before.

The Pembrokeshire Murders cast: Who stars in the series on Netflix?

Luke Evans plays SIO Steve Wilkins

Who is Steve Wilkins? An experienced police detective, Steve Wilkins returned to his home in Wales in 2006 following a stint at Scotland Yard, to take up a new job as Deputy Head of Dyfed Powys CID. Soon after his arrival, he put a team together to reinvestigate two double murders from the '80s, which he hoped to solve with help from new developments in forensic science.

Wilkins quickly set his sights on John Cooper, and along with his team – and with help from ITV journalist Jonathan Hill – he set about trying to convict him before he was released from his current jail sentence for robbery and burglary.

Speaking to RadioTimes.com and other press at a Q&A event to promote the miniseries, Evans said of Wilkins: "One thing about Steve is he's a charming human being, and once you meet him you understand how his team worked all those hours through the nights and spent months away from their families and friends because he's such a good human being and he treated them with respect.

"And that's why he's a great team leader and kept their spirits alive when they were all losing faith and losing hope that they were ever going to find this killer. So he's a great man. I've played some great people and I've played some terrible people in my time but it's always quite nice to play a good one – and Steve Wilkins is definitely one of those."

What else has Luke Evans been in? Evans has a storied career in film and television, having appeared in several Hollywood blockbusters including Clash of the Titans, Fast & Furious 6 and The Hobbit.

Keith Allen plays John William Cooper

Who is John Cooper? Cooper is a serial murderer who, in 2011, was convicted for two double murders on the Pembrokeshire coast, occurring in 1985 and 1989 respectively. Prior to his murder conviction, he had previously spent time in prison for burglary and robbery but was released in January 2009, just four months before his re-arrest.

Cooper was nicknamed 'The Bullseye Killer' by the press because of an appearance he made on the popular '80s darts programme, footage from which was used as evidence against him in order to prove his similarity to a sketch of a suspect, after he had removed all photographs of himself from the period.

Speaking to RadioTimes.com and other press about playing the character, Allen said: "I think what he hated was happiness, people being happy.

"With the couple walking on the coastal path, he must have seen a couple who were just in love, and had everything that he hadn't got. The first scene that I did was the burial scene of my wife, and I met people who knew him who were from that village and saying 'oh you would never have guessed'. Was he the life and soul of the party? No, but he was very polite, he didn't like swearing."

What else has Keith Allen been in? Allen has appeared in a wealth of TV and film projects since the '80s, with some of his most notable credits including films such as Shallow Grave, Trainspotting and The Others.

He's also a prolific small screen actor, having starred in the likes of Bodies, Robin Hood, The Runaway and The Body Farm.

After Cooper was convicted, Hill co-wrote The Pembrokeshire Murders: Catching the Bullseye Killer – the book on which the series is based – with Wilkins.
