A Latino Review source at Warner Brothers has said that the studio wants the Lars and the Real Girl actor to wear that glowing green ring. Now, the concept art I referenced might look a little bit beefy for the thin star, but Hal Jordan was modeled after Paul Newman, at least partially, so Gosling would be a pretty good match for that (should the green dude be Jordan). But even more importantly -- Gosling knows how to make the strange seem natural -- he made a heartfelt and funny film where he was in love with a flipping Real Doll. If he can do that, he can make the green look just as cool as RDJ made Iron Man, and give the same excellent depth to the portrayal.
It's also miles above Seth Green, Justin Long, and David Boreanaz. Agreed?
