The six-week series was a huge hit when it aired on ITV earlier this year, and as the credits rolled on the finale, bosses announced that we’ll be getting more episodes in 2018.
However, speaking to HuffPost UK on ‘BUILD’, Warren confessed that has no idea what’s actually happening next.
“I can’t say anything,” he said. “I honestly don’t know... I don’t know whether they had always planned [for a second series] but obviously with the audience reaction...”
Hinting that he may have other filming commitments when ‘Liar’ is being shot, Warren added: “We may be doing ‘Strike Back’ at the same time so I honestly don’t know how much my involvement will be if any.”
The actor played Tom Bailey, the former boyfriend of lead character Laura Nielson, and he proved to be a key player in the series.
Not only was Tom having an affair with Laura’s sister Katy, he was also key in bringing rapist Andrew Earlham down.
He could also be a suspect for Andrew’s murder, after he was found dead in the marshland at the end of the series.
