Emmett Scanlan has said his upcoming scenes in Hollyoaks Later will take his bad boy character Brendan Brady "to a new level of darkness".
The actor's shady alter ago has a key role in the post-watershed show, to be shown across five nights on E4 this autumn.
And Emmett revealed: "It builds very, very nicely throughout all five episodes. Come episode four and five it takes the storyline to a new level of darkness and black comedy.
"There's some very daring stuff, very ballsy stuff that I don't think has ever been done on Hollyoaks before, so for that reason alone I'm excited as hell."
The Irish soap star has been flying to and from Belfast filming the BBC crime drama The Fall, alongside his Hollyoaks colleagues Karen Hassan and Bronagh Waugh.
Emmett, who plays a detective searching for a murderer, said: "I've had about 10 flights in the last 9 days - that's not an exaggeration. I've been back and forth, back and forth, it's been immense."
He added: "For the first time in a long time I've been cast as a good guy. I'm going from hunting a serial killer to being hunted myself when I'm back on Hollyoaks. It's a massive change."
