Jack Gleeson shares behind-the-scenes fun from House of Guinness

House of Guinness is set to drop on Netflix imminently, featuring Game of Thrones legend Jack Gleeson as Byron Hedges.

Appearing alongside Anthony Boyle, who portrays Arthur Guinness, Gleeson's character is quirky and mischievous - a far cry from his notorious Joffrey Baratheon persona.

During a screening event for the upcoming Netflix drama, which also stars James Norton, Gleeson chatted exclusively to Reach publications about his time on set.

He confessed that some "accidental improv" ended up on the cutting room floor, revealing: "There is a scene where Byron is getting chased through the streets of New York, that was quite a fun sequence.

"There were real chickens I was jumping over. I don't think they actually used it in the moment but I'm getting chased and there is a pram in the way, without a child in it."

"And I shove the pram to block my pursuers and just by accident I sort of said 'pramise!' as if that was some kind of phrase that people say.

"Anyway, I think they made the right decision not to keep that bit of improv in.

"But that was so much fun to play, it was like three days of running around old New York.

"They did up the northern quarter in Manchester. That will be fun to view."

He disclosed that portraying such a quirky character led to some entertaining behind-the-scenes moments.

The actor continued: "I guess the reality is you have to learn your lines and you have to be professional, I do like to do a lot of preparation.

"I guess there were a few days where me and Anthony [Boyle] were vibing off each other, kind of taking the p*** a bit, in a really fun way.

"Maybe there is a bit of light relief there in some of Byron's scenes and I think me and Anthony just have a similar sense of humour so we were just sparking off each other.

"That was really fun because it keeps it fresh for us as actors and that gets transmitted to the audience, I hope."

House of Guinness airs on Netflix on September 25
