Textface alert for these two new posters for Marvel’s Thor movie, completing the set which began earlier in the day with these faceposters featuring Chris Hemsworth and Anthony Hopkins.

Natalie Portman and Idris Elba are pushed both front and centre for these images, and there’s a quiet momentum building for Branagh’s film, though how much it permeates the audience unfamiliar with the comic book is unclear – these posters are striking enough but will they help draw the crowds in the same way the first Iron Man film did?

Thor is directed by Kenneth Branagh and Chris Hemsworth as the title character alongside Natalie Portman, Anthony Hopkins, Kat Dennings, Idris Elba, Stellan SkarsgÄrd, Ray Stevenson and Rene Russo.

We can expect to see it in the UK 28th April 2011.

Synopsis: Thor, a powerful but arrogant warrior, is sent down to Earth has punishment for reigniting a reckless war. But after a dangerous villain from his world sends the darkest forces of Asgard to invade Earth, the hammer-wielding Thor will learn what it takes to be a true hero in order to save mankind.

Here they are, IMDb had ’em first.

DR. JANE FOSTER: A brilliant and talented young scientist, Jane began her career doing particle research at Culver University in New York. She continues to do post-doctorate work there in the field of astrophysics. Most recently, she applied for and was given a grant to study anomalous particle phenomena in Puente Antiguo, New Mexico.

HEIMDALL: The gatekeeper and sworn guardian of Asgard, Heimdall can focus his extraordinary senses on any world across the cosmos, seeing and hearing all that transpires. These gifts, along with his intimidating size and battle prowess, make him the only Asgardian fit to keep watch for potential threats and defend his kingdom from those who would destroy it.

I’m actually hoping that this is a subtle tease for Branagh’s own stylistic preference for Thor – that this is how the film will look when it appears in cinemas,

But that probably won’t happen. Shame.
