Duncan James found it "hard" to go from "violently" killing someone in 'Hollyoaks' to doing his supermarket shopping later in the day.
The Blue singer played serial killer Ryan Knight in the Channel 4 soap but admitted it was "very bizarre" having to act out murdering someone in the programme and then altering his mindset when he hit Tesco for a spot of after-work shopping.
He exclusively told BANG Showbiz: "There was lots of intensity with Ryan's character, which I found quite hard personally.
"You've got to go from killing somebody in your day job to being a murderer filming it from all different angles, and then you are just going to do your shopping in Tesco.
"It's very bizarre because you've gone from one mindset of getting yourself into murderous world and strangulating somebody and killing them quite graphically and violently.
"Obviously a lot of it doesn't get shown in the edit because they are not allowed to show it.
"But when you do it it's really weird."
Duncan previously starred opposite Sheridan Smith in 'Legally Blonde' on London's West End, and he would love to tread the boards again in the near future.
He added: "I've had some interesting offers since 'Hollyoaks', it's been great.
"Straight after that I had the LGBT Awards with Mel B and just bits and bobs really.
"There are a couple of acting roles going back into theatre that I am looking into at the moment, so we will see what is going to happen.
"I love theatre and that is where my true passion lies."
