Since then, he has gone on to star in dozens of films including the gruesome flick The House That Jack built in 2018.

He was seen on the red carpet for that project with his girlfriend of nearly six years, Roberta Mastromichele. 

The couple first started dating in 2014, and though they sparked rumours of engagement in 2017, they are yet to publicly confirm any plans to wed.

Last year, Matt defended his decision to star in the Lars Von Trier Film The House That Jack Built, after it sparked walkouts following its premiere at the Cannes Film Festival.

Speaking in an interview in MR PORTER’s weekly digital magazine The Journal in November 2018, he admitted: ‘I’m OK that people are upset. 

‘It’s meant to be upsetting to you, and you should know, if you’re going to see this that it is going to some very dark, disturbing places.’

He added: ‘But I think it’s a good film. Really good. And I’m glad that I did it.’

In the film, Matt stars as Jack, a serial killer with more than 60 deaths to his name who relishes bloodshed and plots increasingly horrifying ways to inflict death.
