You may call the movie a guilty pleasure, but this cover is high-class business! I love the mood you've created.
Maybe you could move the design to the right just a tiny bit or shrink the whole thing by 1% so that the side of Brosnan's head isn't quite so close to the edge?
The only other element I'm not quite sold on is the title treatment -- it would look cool on the screen as an opening title, but on a cover it's perhaps a bit too much. It might be the Outer Glow... the orange pairs beautifully with that green tint, but would plain white/gray text work? Maybe with a little bit of texture? Or, going in the opposite direction, it might work to push it even further and make it the focal point of the cover by giving it 3d depth (perhaps with a rock texture) along the lines of some of Kernie's greatest hits, for example.
I'm looking forward to seeing where you take this one, the movie is good fun and you've got a great design in progress.
