Talking of Enemy, there is an interview here with its actress Sarah Gadon, which I haven't read as it has spoilers. In this interview with Denis Villeneuve, the director tells us it's perfectly all right to be confused by Enemy. It also contains a great bit from Denis about working with Jake:
'I was looking for an actor, I was looking for a strong actor, English actor — Anglophone, I mean, an English-speaking actor — I was looking for somebody profound, somebody that would have the strength, the ability, the creativity [to take on the role]. And I had seen him in Donnie Darko. I knew that he was playful, willing to do strange things. I knew that he was a strong actor because of Brokeback Mountain. He blew me away how strong he was, I think that is one of the most beautiful performances of the decade, what he did in that film. So difficult and so precise. I love Jake in Jarhead… every time I had seen him on the screen, I was fascinated. I was starting the casting, I learned that he was available, so I took a chance. I just took a chance. I wrote him a big, long letter, sending him the script. And he invited me to drink a glass of wine with him in New York, and we drank the whole bottle, and it was the beginning of a beautiful friendship. I think what interested Jake in the project was not so much the story, but the process. What we will try to do with this movie.'
There is another clip from Enemy here.
