Love/Hate star Tom Vaughan Lawlor has revealed that the most difficult scenes to film are those featuring aggression against women.
The actor, who plays Nidge in the top gangland drama, has been verbally abusive towards a number of female characters on the show including Siobhan, Janet and Debbie.
"It's a bizarre thing listening to yourself being aggressive, especially aggressive against women," he said.
"It's very strange. I've got three sisters and my wife, and it's very strange to be aggressive towards women.
"I found them the most difficult scenes. All the other stuff [was tough] but especially towards women I find it hard. It's tough to film," he admitted.
And after filming such intense scenes, Tom (37) feels he has to come down from playing gang leader Nidge.
"It's usually just coming home and doing family stuff which is lovely - just being with Freddy my son and him laughing," he said.
"And just watching boring things with my wife on TV, and having a bit of food. My wife is brilliant at de-stressing me."
Freddie featured in the third series, playing Nidge's son, whilst his father, also an actor, played the priest in the second episode.
And Tom, who is now starring in Howie The Rookie at the Olympia Theatre, told the Ray D'Arcy Show that he is totally different from Nidge - with people finding it odd when they hear him speak in real life.
"Sometimes you get slightly odd looks or double takes. For the most people are very kind," he said.
"I've had it myself seeing actors who you think are one thing, then you meet them and they are totally different. It is quite jarring, very bizarre dynamic.
"You are seeing these people [on TV] in your homes, and you go, wow they are this person. Then you meet them in a different context," he added.
Meanwhile Tom revealed he actually hasn't watched any of the fifth season - but does expect a sixth will come.
"I haven't seen this season. I usually watch every season before they go to air," he admitted.
"This year I was doing a play and I was very busy, I didn't get round to seeing it this year. "I literally haven't seen anything. I've only seen bits and pieces from stuff we did," he added.
