Daniel Mays

The actor portrays John Worboys – dubbed the “black cab rapist” – in the upcoming series

Daniel Mays has admitted he was “absolutely terrified” when he read the script of his new ITV drama Believe Me.

The actor plays convicted offender John Worboys – who was dubbed the ‘black cab rapist’ after preying on women under the cover of being a licensed taxi-cab driver.

He was convicted in 2009 for crimes including sexual assault and drugging with intent against 12 women.

“I actually underestimated how much it was going to affect me,” Daniel said as a first look image of him as Worboys was released.

“I’ve been a professional actor for 26 years, so I’ve done a lot of true crime and played a lot of wrong ‘uns. When I got these scripts, it absolutely terrified me, because I’m a father myself.

“My head immediately went to my 13-year-old daughter Dixie. She’s venturing out, going on trains, and before long, no doubt she’ll be in the back of a taxi. So as a father, I found it an incredibly disturbing and terrifying read.”

He continued: “It was a difficult thing to have rolling around in my head before filming.

“It was a very isolating character to play, by its very nature. When I was announced to play him, I got this tirade from family and friends and work colleagues who can’t quite believe it, going, ‘Why would you want to play something like that?’ So, the challenge was to humanise him, really, and that was a very difficult and unsettling thing to take on.”

The four-part series, filmed in Cardiff, focuses on the ordeal of Sarah (played by Peaky Blinders’ Aimée-Ffion Edwards) and Laila (played by Raised By Wolves’ Aasiya Shah), who reported sexual assaults by Worboys, and how their allegations were not thoroughly investigated.

ITV said it “tells the story of how the victims of one of the most prolific sex attackers in British history were failed by the system”.

Danny, known for Des and A Thousand Blows, said there’s “always a huge responsibility” playing a real person on screen, but that this was “a whole other level”.

He explained: “This is told from the perspective of the victims, and for them to tell their truth, have their stories told – the ordeals that they went through and the fight they took on against the Metropolitan Police and the court systems.

“So, when you’re dealing with that, the onus was on me to get it absolutely 110% right. That was paramount to me.”

Believe Me is coming soon to ITV1
