Martin Compston reveals his one problem with 'Our House' co-star Rupert Penry-Jones

Martin Compston has admitted he had one small problem with Our House co-star Rupert Penry-Jones - the actor was towering over him in fight scenes.

Line Of Duty star Compston, who is 5ft 8, admitted it was a common issue for him every time one of his characters came to blows on screen.

The actor, who also recently starred in submarine thriller Vigil, said of Whitechapel star Penry-Jones: "He has had an amazing career. He has been there and done it. He’s such a pro.

"In the hands of a lesser actor, his part could have veered towards a parody, but he played it brilliantly.

"My only problem is that he’s so tall. It seems that any actor playing a character I have a grievance with and have to fight on set is always over 6ft 2!"

Our House has been adapted from Louise Candlish's bestselling novel for ITV and features Compston, 37, as Bram, a man with secrets to hide who has gone missing at the start of the story when his estranged wife Fi (Tuppence Middleton) discovers he has sold their family home without her knowledge.

The couple had been alternating living in the house as part of their joint custody arrangement, but Bram finds himself blackmailed over a previous dark secret while Fi begins a relationship with the mysterious Toby (Penry-Jones) who turns out to be hiding plenty himself.

Speaking about the emotion involved in his role, Compston said: "It is relentless. There are some huge, heavy emotional scenes. You have to be careful that life doesn’t imitate art.

"But I did still take it home with me a bit. When you’re crying all day, it can seep into you. You need people to pull you out of it. That’s why it’s important to have a strong family around you."

However, he added: "Bram is a joy to play. We’re in acting for these roles. He has so many contradictions. When people see it, they’ll realise what I’m talking about..."

Our House begins on 7 March at 9pm on ITV.
