According to Harry Knowles over at AintitCoolIcan’tSpell, Jackie Earle Haley (Watchmen‘s Rorschach) is “on the list” to play “Sinestro” in “the Green Lantern movie.” (*air quotes*)

I’m putting this in the caveat as a rumor [??] – as opposed to a rock solid, take it to the bank story. Right now, Martin Campbell is in the process of finalizing the rest of the cast for GREEN LANTERN to surround Ryan Reynolds with. And I’m not sure why, but I’ve just hit the point where I’m giddy and hopeful about a GREEN LANTERN movie. This story came from someone working on the film. That part is solid, what isn’t – and won’t be till it all gets finalized is the fact that JACKIE EARLE HALEY is leading the list to play SINESTRO!!!

Meanwhile, Collider talked to Jackie Earle Haley himself about it, and Haley says he hasn’t heard anything.  He also denied ever screen testing for the movie, and didn’t bite anyone’s face or anything, it was really pretty disappointing.  Oh yeah, so Sinestro:

Sinestro is the former mentor of Hal Jordan and the arch-nemesis of the entire Green Lantern Corps. Sinestro first appears in Green Lantern (vol. 2) #7 (July-August 1961). He is also revealed to be the father of his successor as Green Lantern, Soranik Natu, in Green Lantern Corps (vol. 2) #35 (April 2009).  The visual appearance of Sinestro was based upon British actor David Niven.  In 2009, Sinestro was ranked as IGN’s 15th Greatest Comic Book Villain of All Time.

And there’s another 3,000 or so words of Sinestro facts that would be embarrassing for a grown man to know over on Wikipedia.  There’s a rich mythology, which is sort of surprising for a character named “Sinestro”, who sounds like he should be a guy on a Mexican soap opera who looks like Wario.
