The 40-year-old actor, who is an executive producer on the HBO series, said that he is focused on finding a way to turn it into a feature film.
He told Us Magazine, 'I said if I had to finance it myself, I would do it. I was looking at [a promo clip from HBO] and it looks like a movie to me… It's the f**king greatest thing I've ever seen.
'I certainly hope this has a chance to become a feature film. People are always complaining that the episodes are too short.'
The show's eighth and final season premieres July 24.
