It's the drama that gripped the nation last year, and now back for another series Broadchurch is promising just as many twists and turn this time round.
Speaking on ITV's Lorraine earlier today, Matthew - who plays Joe Miller on the show - claimed that producers made him wear a disguise while filming, as they were so intent on keeping details of the new series firmly under wraps.
Last year, Broadchurch raked in 9.1 million viewers on its debut, and fans were hooked as the hunt for schoolboy Danny Latimer's killer unfolded. In the series finale, Matthew's character was unveiled as the man behind the murder, but following the opener of series two on Monday it seems all is not as it seems.
He may have previously confessed to the killing, but Joe Miller provided the first twist in the series as he pleaded 'not guilty' to the charges against him. Setting the scene for what's in store, he later said: "Nobody's innocent. Everyone's hiding things."
Promising a shocking series ahead, it's no surprise then the show's producers have made sure not to let anything slip... even if it calls for extreme measures.
Speaking to Lorraine Kelly, Matthew said: "When we were filming, I did have to go around in a wig and glasses with my hood up, just in case.
"Your name is printed on every page of your script, so if you're careless they can go 'oh that's your script... fired!'"
Despite his character being named and shamed of murdering an 11-year-old boy, Matthew did admit to Lorraine he hadn't received any backlash from the public since the revelation.
When asked if he had experienced anybody shouting at him in the street, he replied: "No, not yet... which is good!"
Although, he did reveal he had to brief his children about the show just in case.
He added: "I briefed our kids just before the revelation and said 'look there's this programme, it's been quite successful, people might come up and say 'you're a killer', but I'm not a killer it's pretend'.
"The [children] get it, they know that [acting is] what we [me and my wife] do. They know it's pretend so they're not affected by it."
Broadchurch continues next Monday 12 January at 9pm on ITV.
