Here's what Mark Strong has to say:
On the question if he has seen the film yet; “I haven’t seen it yet,” says Strong, but I’ve seen the artwork and if they can get that right, it’ll be astonishing.”
Comparing it with John Carter of Mars CGI direction:
“They’re very similar in sense that they’re like trying to make a jigsaw puzzle with two thirds of the pieces missing because so much of it is CGI. As Andrew Stanton says, ‘I’m not in post, I’m in principle digital photography.’”
On the earth/space ratio: “On Green Lantern two thirds is on Earth and a third is in space. All my stuff is in space, so all my scenes were in a big green room.”
