'Green Lantern' News: Jackie Earle Haley as Sinestro?

More 'Green Lantern' news this week. Last year, the rumors flew about Jackie Earle Haley (Watchmen) playing Sinestro in the film. Haley was first reported to be in the film, then that was shot down. He is. He isn't. He is. He isn't. It was like a couple of five year olds arguing. Now comes Drew McWeeny at Hitfix, who is sticking his neck out regarding Haley:
"Jackie Earle Haley is the only choice for Sinestro by the studio."
McWeeny also said that while the deal isn't signed:
"I'm willing to say that Haley is the guy."
Whether or not Haley is Sinestro shouldn't be the question here. The question should be: Why the heck is this film trying to tackle multiple villains? HAS NO ONE LEARNED FROM 'SPIDER-MAN 4'? Less is more, studios. You spread the film out and people walk away mumbling.
