A fair few months ago, we brought you the news (
http://www.movie-moron.com/?p=9265)of the main characters to be expected to take part in the upcoming superhero flick
Green Lantern. Well, now we can reveal to you the actors cast in those roles.
Hal Jordan/ Green Lantern

This one has been known about the longest. Ryan Reynolds,
Wolverine's Deadpool, is going to step into the green-and-black spandex for the title role. It makes sense - he's a very good actor with a variety of roles under his belt. Hell, Deadpool was on screen for all of three minutes and became easily the best part of
Wolverine, thanks entirely to Reynolds' impressive handling of a terrible script.

Carol Ferris

Hal Jordan's boss/ love interest will be played by Blake Lively, best known for playing Serena van der Woodsen in TV's
Gossip Girl.

Hector Hammond

In talks for the role of love rival/ drooling psychic supervillain is Peter Sarsgaard, best known for
Orphan and the forthcoming
Knight & Day. Should be interesting to see how he manages to inflate his head to play the role properly.

Now for the most interesting bits of news trivia: director Martin Campbell (
GoldenEye,
Casino Royale) revealed in a video interview that
Watchmen/
A Nightmare On Elm Street's Jackie Earl Haley is
not in the running to be Sinestro, the series' most prominent villain. Instead, he wants Mark Strong as his Sinestro.

Mark Strong was most recently on screens in Guy Ritchie's flawed-but-so-much-fun-it-was-kind-of-forgivable
Sherlock Holmes, where he became such a good villain it was a shame he wasn't used more. BUT! Here's another interesting tidbit of information - Martin Campbell has hinted that Sinestro
won't be the chief antagonist in the first film. Instead, it stands to reason that Hector Hammond will be the baddie - for the first film at least - with Sinestro slowly being corrupted throughout the proceedings. This works well with us, and any opportunity to see Mark Strong as a villain is always a plus.

The quote that dropped the hint:
"I think it will stick closely to the origin story, but we all know Sinestro, for an example, is a character who goes over to the dark side, and of course, Carol, played by Blake Lively, in later versions becomes a bad guy as well. I think people will be able to see forward to the characters that in the comic went on to (become bad guys)... but people will be ahead of us on all that I think."
This leaves the role of Hal Jordan's mentor Abin Sur currently unfilled. I'd go for Ben Kingsely - he was in
Bloodrayne and
The Love Guru, he's gotta be going cheap. Plus he's bald.

But Campbell has let slip yet
another piece of information - two of The Green Lantern Corps (the good guys)
alien team members are going to be in the movie, Kilowog and Tomar-Re. This is especially confusing considering that Kilowog looks like this:

And Tomar-Re looks like this:

This is clearly going to be set in a very different world to the ones set up by
Iron Man and
The Dark Knight. Luckily, Campbell knows how tough selling this movie to those without access to Wikipedia is going to be:
"Kilowog will be... Tomar-Re is in it. Sinestro is in it. Abin Sur is in it. All the origin people. Carol, of course... All the main characters are there, and it's a complex story. The origin story of Green Lantern is complex, probably one of the most complex, which makes it a challenge to get it right."
