The Might of Asgard and the New Day Co-Op.

Casting continues to fill out for Kenneth Branagh’s Thor: Apparently Idris Elba will play Heimdall (Asgard’s bouncer, basically), and Stuart Townsend, Ray Stevenson, and Tadanobu Asano have signed up as Fandral, Volstagg, and Hogun respectively (Fandral, Hogun and Volstagg.) Stringer Bell and the Warriors Three join Chris Hemsworth, Tom Hiddleston, Natalie Portman, Jaime Alexander, Colm Feore, Anthony Hopkins, and Stellan Skarsgaard.

Norsemen and Networks.

Casting for Kenneth Branagh’s take on Thor fills out, with Jaimie Alexander and Colm Feore joining the cast. Alexander plays Sif, while “Feore’s character is shrouded in mystery, though it is known to be a villain.” (That spells trouble to me — Be it stage or screen, Feore can be super-hammy.)

Whoever Feore is playing (Mephisto?), it’s not Loki — That would be Tom Hiddleston, appearing alongside “Papa Kirk” Chris Hemsworth as Thor and Natalie Portman as Jane Foster.

Meanwhile, the strange Aaron Sorkin-penned, David Fincher-directed Facebook movie, The Social Network, gets a cast in Jesse Eisenberg, Justin Timberlake, and Doctor Who alum Andrew Garfield (also soon to appear in Gilliam’s Imaginarium.) “Eisenberg will play Facebook CEO Mark Zuckerberg; Timberlake will play Sean Parker, the Napster co-founder who became Facebook’s founding president; and Andrew Garfield will play Eduardo Saverin, the Facebook co-founder who fell out with Zuckerberg over money.

Ancients of Asgard.

Casting fills out for Kenneth Branagh’s Thor — there’s a phrase that should stay weird for awhile — with the titular hero to be played by Chris Hemsworth (recently George “Papa” Kirk in Star Trek) and Branagh veteran Tom Hiddleston as Loki. Well, they both look the part, at least. So far, so good.

But in time you see things clear and stark.

In Marvel news, the the teaser for Jon Favreau’s take on Iron Man, with Robert Downey, Jr., Gwyneth Paltrow, Terrence Howard, and Jeff Bridges, is now officially online. (Basically, it’s a shortened version of the Comicon clip.) And has Matthew Vaughn found his Thor in Kevin McKidd of HBO’s Rome and Trainspotting? Possibly maybe…if so, that’s not half-bad.

Hurt v. Hulk, Norrin from Cincinnatti, Matt takes Mjolnir?

In Marvel comic-to-film news, William Hurt joins Louis Letterier’s increasingly-stacked The Incredible Hulk as Gen. Thad “Thunderbolt” Ross. (The movie, it may be remembered, already stars Edward Norton, Liv Tyler, and Tim Roth.) And, also rumored to be in the works: a Silver Surfer film written by J. Michael Straczynski of Babylon 5 (Will the character have any life in him after FF2 this weekend? I somehow doubt it) and a Thor film directed by Matthew Vaughn of Layer Cake and Stardust. (Ooh…can we get Beta Ray Bill?)

You’re so Iron and you don’t even know it.

Among a slew of recent announcements, including the writers of Thor (Mark Protosevich of Poseidon), Captain America (David Self of Thirteen Days), Nick Fury (Andrew Marlowe of Air Force One), and Hulk-2 (Zak Penn of, sigh, X3 and FF) — as well as official word on Edgar Wright’s Ant-Man — Marvel’s Avi Arad says Jon Favreau will helm Iron Man.
