Anton was interview by Indiwire, i have only posted the part where he talks about 'Life'.
Link to full interview at bottom of post.

In “Life,” Dane DeHaan will be playing James Dean. How difficult was it to cast someone in that role?
It was difficult. Also I think for the actors it’s very difficult to step in his shoes. But Dane DeHaan plays it well. He’s a tremendous actor. I don’t think he wanted to do it initially. He wouldn’t take a meeting with me because he didn’t want to be persuaded. But luckily he came to me and he was persuaded. He’s amazing.

He’s great in “Kill Your Darlings.”
Yeah, and “Place Beyond the Pines.” I haven’t seen “Spider-Man [2].” “Lawless” I have seen. And he’s in “Devil’s Knot” and “Life After Beth.” I haven’t seen that. I was in Sundance but I didn’t manage to see a single film.

What about Robert Pattinson’s work in the movie?
Rob and Dan very different kind of actors. They’re very, very different kind of people in the film, so it was fantastic. They were so different naturally. For Rob to play a photographer is quite interesting because he’s being chased by photographers all the time. Rob is of course a film star, but he likes to be seen as an actor, so he works very hard to be an actor and be valued as an actor. And in the film he plays this photographer who wants to be seen as a great photographer. So I think there’s a parallel there that’s helpful.

He’s made a lot of interesting acting choices, “Cosmopolis”…
...Yeah, “The Rover.” I hear that “Map to the Stars” is a really great film. I am looking forward to seeing it.

I was hoping to see “Life” announced as part of the TIFF 2014 lineup.
Yeah, I was hoping that too, but we are too far from finishing, because we finished [shooting] in late October.

Will we see it at on the fall festival circuit anywhere?
I reckon it will be 2015.
