Matt Damon thinks moviegoers aren't aware "of how much power they have"

The Hollywood star told 'Extra': "In the '90s there would've been a number of films of this scale. There would've been a number of these every year, and they've been decreasing, obviously, over the years.

"The only way to remedy that is to make these films and to put them in theatres and for moviegoers to go support them. I think people might not be aware of how much power they have as moviegoers. If people go and see it, we can make more of them."

Matt actually appears in the new movie alongside Cillian Murphy, and he relished working with his former 'Oppenheimer' co-star.

The actor also admitted that he had no hesitation about throwing his support behind the film, which is an adaptation of Claire Keegan's novel of the same name.

Matt - who is one of the highest paid actors of all time - shared: "We were just getting Artist Equity off the ground, I asked [Cillian] if he had anything and he says, 'I happen to have this really wonderful script...'. I'm like, 'Oh, my God, this is exactly what we are looking for.'

"I read the script and immediately sent it to Ben ... It was a very embarrassingly easy decision for us to finance this film. We all knew each other, and we know the quality of work these people do."
