Hero Complex gives us the first official photo of the three stars of Marvel’s upcoming Thor film being directed by Kenneth Branagh (Hamlet, Mary Shelley’s Frankenstein).

The photo shows Norse God Odin (Anthony Hopkins) alongside his two sons, Thor (Chris Hemsworth) and Loki (Tom Hiddleston). It’s also worth noting that this is our first look at Thor wielding his famous weapon, the mighty hammer Mjölnir. It looks very similar to the previous unofficial photoshop images released a few weeks back.

The article goes on to discuss Branagh’s decision to add 3-D to the film in post-production, and mentions that Captain America director Joe Johnston test filmed some 3-D scenes for the upcoming First Avenger film. Both directors confirm that their films will be in 3-D, and that they hope to create a better experience for viewers than other more recent conversion attempts.

I think the shot looks amazing and you can really see the detail and effort Branagh is bringing to the table.  With the San Diego Comic-Con just around the corner, hopefully we’ll get a chance to see the film in action.

Thor is set to hit theatres May 20, 2011.
