Joanne Froggatt has ruled out a season three of the psychological thriller Liar.

The highly-anticipated second season is set to return to Virgin Media One at 9pm on March 5 - and will follow the case of who killed Andrew Earlham. And Joanne, who plays Laura Neilson, said that the reaction to Liar was the "biggest reaction" to anything that she had done. “I was getting on a flight during the first season and 11 people came up to me and said: ‘Oh my God, we love it,'" she recalled, speaking to The Sun's TV Mag. "It’s lovely to think you’ve been a part of something that people are invested in and so excited about. It’s a really nice feeling and I’m proud we’ve done another series." She added that season two will be "the end of Andrew and Laura's story." "I think it’s really honest with the viewers. There’s nothing worse than investing your time in something and then you get to season three and think: ‘Oh, it’s all gone too far. I don’t believe it,’" she said. Meanwhile, Ioan Gruffudd, who plays Andrew, said that season two was "a lot harder emotionally". “In the first season Andrew didn’t think he was evil so, to me, I was just playing someone who thought: ‘I’m not doing anything wrong,'" he explained. "This season he’s been found out – he’s been caught and he’s unravelling. It’s probably one of the hardest things I’ve ever had to do as an actor. It was emotionally draining on a daily basis."
