With Ryan Reynolds cast as the titular lead in Green Lantern the feature-film (and likely franchise) is officially in production. The following casting calls went out a few weeks ago:-

CAROL FERRIS26-32, a smart and attractive woman with an MBA. She started as a pilot and now runs Ferris Aircraft. She is a workaholic...FEMALE LEAD

DR. HECTOR HAMMOND
27-35, Character actor who is austere and impersonal, he is real "scummy." He is a pathologist and also the son of a Senator.

SINESTRO
Mid-30s to Mid-40s, he is smart, tough, intimidating and in great physical shape.

ABIN SUR

Mid-30s to mid-40s, he is a great warrior

The casting call leads me to assume that the story will be roughly based on comic-book virtuoso and veteran Green Lantern scribe Geoff Johns recent Secret Origins storyline which fleshed out Hal Jordan's beginnings with the Lantern Corps. With that story in mind I set about hypothesising who could fill the roles listed above and beyond.

Michelle Monaghan as Carol Ferris

Carol is a tough and savvy bus

iness woman who has known Hal Jordan since they we

re children. As Jordan's boss and love interest Ferris needs to be played by, not only a beautiful woman, but someone with a little edge. Based on her roles in Kiss Kiss Bang Bang and Gone Baby Gone I can see Michelle Monaghan filling the shoes of the workaholic business owner.

Michael Fassbender as Dr. Hector Hammond

Fassbender was great as the suave British soldier in Inglorious Basterds and the middle-class protagonist in the frightening Ed

en Lake. I think he could do a great turn as the slimy doctor turned deformed super villain an

d I think has sufficient depth and range the play the character straight where there is a danger he might be viewed as comedic.

Guy Pearce as Sinestro

Once regarded as the greatest Green Lantern, Sinestro came at odds with the corps when it was discovered that his sector (a sector of space is assigned to each Lantern to protect) was ke

pt so peaceful using a controversial method: fascist dictatorship. Initially however Sinestro was Jordan's mentor in the corps, which is the role is assume he would be l

argely filling for a good portion of the film.

Pearce has the acting chops to flesh out the potentially panto-esque character as both a leader and mentor figure and calculating villain. Check out his roles in The Count of Monte Cristo, Traitor and The Proposition to see why I think he's the right man for the job.

Daniel Craig as Abin Sur

Abin Sur will be a small part in the film but, just as Dr Erskine is in Captain America, an i

mportant role. Abin gaves Hal Jordan the ring that makes him become a Green Lantern. A role like this should be a big name in my view, so why not turn to the man that Green Lantern director Martin Campbell catapulted into fame as the re-envisioned James Bond in Casino Royale. Craig is in the right age group and could certainly be cast as the great warrior the casting call asks for.

If all does to plan then many more GL characters will hopefully be turning up in GL, Here are the characters that I would like to see turn up.

Anthony Hopkins as Gathnet

The Guardians of the Universe are the Green Lantern's bosses, they are little blue men with balls huge enough to declare themselves as the universes protectors. The Guardian who is best known to fans is Gathnet. Gathnet is the most human of the Guardians and takes Jordan under his wing. Nobody plays a wise mentor figure like Anthony Hopkins, check out his roles in The Mask of Zorro, Meet Joe Black for his more kindly roles.

Ray Winston as Kilowog

While the huge and literal monster would have to be a creation of CGI, but Winston would be great voicing the gruff drill sergeant of the corps. He needs to be a fearsome yet lovable figure and Winston would fit the role perfectly.
