With two full trailers, a Super Bowl commercial and plenty of stills, posters and other media, there’s not too much more for Marvel Studios to unveil about Thor without entering heavy spoiler territory.

Set to kick off the summer movie season of 2011, Thor is the first of four major comic book releases, and the first of three from the Marvel Comics brand. For a closer look at Natalie Portman and some of the main Asgardian characters, we have several new Thor posters.

The following six posters, released one-at-a-time by IMDB,  feature key characters of the film’s cast and include Thor (Chris Hemsworth), Loki (Tom Hiddleston), Dr. Jane Foster (Natalie Portman), Heimdall (Idris Elba), Sif (Jaimie Alexander) and Odin (Anthony Hopkins).

When it comes to the images of Thor and Heimdall, they are the exact same shots from previous stills and posters. In fact, the character poster featuring Hemsworth below is identical to the previously released posters from the beginning of the month, sans the red overlay. The other character poses you may also recognize from Thor character banners.

Ever since the initial mixed reaction to Thor’s costume in the adaptation, the Asgardian designs have grown on us and we can all appreciate the work that went into keep the characters and attire true to Marvel’s source material. The posters are incredibly simple in design, and while I’m sure we’d all love to see more artistic comic book-esque poster art, the close-ups of the characters and their respective features do speak for themselves, especially in a film boasting a cast a strong as this that can sell mainstream audiences.

Directed by Kenneth Branagh and written by Ashley Miller, Zack Stentz and Don Payne, Thorstars Chris Hemsworth, Natalie Portman, Anthony Hopkins, Tom Hiddleston, Stellan Skarsgård, Kat Dennings, Idris Elba, Ray Stevenson, Rene Russo, Clark Gregg, Jaimie Alexander, Colm Feore, Tadanobu Asano, Joshua Dallas and Joe Gatt.
