As you’re crafting this fifth season, are you looking at an endgame?
I’m beginning to seriously think of an endgame, I think it’s essential. This is a series and a story that in its inception was never designed with a grand design of where Ray Donovan was going. That was the design. [..]
So specifically, you never want to end this show with Ray’s death?
Oh lord, no. No, no. That would be the easy way out of the storytelling.
Does season five feel like the end or are you looking beyond?
[..] My first priority is to dream up a really gorgeous year five, to make sure it delivers a show that, should it live for a sixth, seventh or eighth season, will be satisfying to the audience and artists. We who are making it need to be engaged and in love with it otherwise the audience won’t like it.
