Back in October we reported that Jackie Earle Haley was about to sign on to play Sinestro in Martin Campbell's Green Lantern, although we updated later on that Haley hadn't even heard of the part at the time. Now HitFix is reporting that Haley is the front-runner to play Sinestro.
And I'm hearing that based on the relationship they have with him from Watchmen and A Nightmare On Elm Street, Jackie Earle Haley is the only choice for Sinestro by the studio.
The site also went on to say that Sinestro might not have a huge part in this film, but will set up future sequels where he will surely have a bigger role. It was also said that it wasn't clear at what stage of negotiations Haley is in for the role, but the site was confident enough to say, "I am willing to say that Haley is the guy."
