With just a few days until the Line of Duty finale, fans are pining to find out who 'H' really is.
Kelly Macdonald made an appearance on BBC Breakfast on Monday to discuss the latest developments in the hit cop drama following a tense episode that saw her character DCI Joanne Davidson discover her paternity.
Eager to get some juicy details out of Kelly, presenter Dan Walker quizzed the actress on a number of as-yet-unsolved parts of the case.
"Can I press you on some concerns that some of our viewers have? Do you know who the fourth man is?" Dan asked.
"No comment," Kelly replied.
"Is Jo Davidson going to make it through to the show's finale, are you going to survive the last episode? How long has Marcus been dead for?" he continued.
“No comment,” Kelly answered.
Dan then asked: 'Who do you think your real father is? What's under that concrete floor? Is Marcus actually dead? Is Hasting bent?" to which Kelly responded: "No comment."
At the end of the interview, she burst out laughing, and Dan said: "I’m giving up, this is pointless."
Kelly also spoke of the challenges she faces during filming, admitting it was "unlike anything she'd ever done."
She said: "You’re aware that the glass box scenes are really pivotal and Adrian [Dunbar, who plays Ted Hastings] told me at the beginning that it’s a chance for the actors to flex their muscles a little bit – the lead actors who come in – so it was really daunting.
"We filmed it over two days, and the first day it was all on me and we did 50 camera setups. That is extraordinary. Filming the scene took half an hour, so you could only fit so many takes into the day. It was unlike anything I’ve ever done."
