Aidan Turner leads ITV’s ‘The Suspect’ as troubled Dr. Joe O’Loughlin

The Suspect is the latest ITV psychological thriller based on the Michael Robotham novel of the same name, with an exciting and recognisable cast!

The show centres around Doctor Joseph O’Loughlin who appears to have it all – a beautiful wife, a loving daughter and a successful career as a clinical psychologist.

But when he is brought in as a consultant on a murder case, his whole life starts to unravel.

So, with a show filled with recognisable faces how do you know everybody from The Suspect cast?

Aidan Turner plays Doctor Joe O’Loughlin

The 39-year-old Irish actor, Aidan Turner, is the leading man on the ITV show as Doctor Joe O’Loughlin.

He’s best known for his role as the titular character in BBC’s Poldark.

Turner made his on-screen debut back in 2009, taking on a starring role in the BBC’s acclaimed Being Human, in which he played Mitchell for three seasons.

Turner is also well-loved for his portrayal of Kíli in the Hobbit series of films. He also played Luke in the adaptation of Cassandra Clare’s Young Adult novel The Mortal Instruments.

He’s also recently starred as Leonardo da Vinci in the popular Amazon Prime Series Leonardo, and also recently guest starred in Matt Berry’s Toast of Tinseltown.

He says this about playing Joe: “Joe is definitely a flawed character. Which is interesting to play. He regularly makes impulsive and risky decisions knowing that there could be consequences for this later.

“Sometimes this behaviour pays off for Joe and other times it just seems to make things more complicated for him.

“This makes Joe unpredictable and sometimes unreliable which is refreshing to play in a protagonist. If that’s what he is.”

Shaun Parkes is DI Ruiz in cast of The Suspect on ITV

The 49-year-old actor plays Detective Inspector Ruiz.

Last year the British actor was nominated for a BAFTA for his lead role in Steve McQueen’s anthology series Small Axe.

The actor is also known for his role as Bill Rumer in the 2006 film Notes on a Scandal, as well as his role as Izzy in The Mummy Returns.

Shaun shares this about his role on The Suspect: “I’ve played a few TV police detectives on screen and have done so many that for a while I thought, ‘I don’t want to play another detective.’

“I thought I had done enough. Then this story came along. You don’t really know in the first couple of episodes what it’s about.

But I realised that The Suspect is really trying to say something.”

Anjli Hohindra plays DS Riya Devi

She’s also known for her role as Queen Skithra in Doctor Who, Nadia in Bodyguard, Zaheera Kamara in Bancroft, and Archie in the recent The Lazarus Project.

The actress shares this exciting preview of the programme: “I truly did not expect the ending of The Suspect. I give myself three guesses at the beginning of a thriller.

“And I was completely wrong when it came to The Suspect.”

Adam James plays Dr Jack Owens in The Suspect on ITV

Another Vigil alum joins The Suspect cast. Adam James plays Dr Gerald Owens on the show, known as Jack.

He is Joe’s Doctor, who diagnoses him with Parkinsons’ at the start of the show.

His other recognisable roles include his role as Neil in Doctor Foster, and his role as Julian in BBC’s acclaimed hit I May Destroy You.

He recently starred as Jack Turner in BritBox’s Hotel Portofino.

This is what Adam James says about his role: “Jack’s life has been intertwined with Joe and his wife Julianne’s lives for many years, having also been best man at their wedding.

“Both Aidan and I played the genuine friendship and history of both men. But any long-term friendship always has its tensions.

“We’re equally thrilled and delighted for our best friend’s successes…and sometimes failures.”
