James Gunn's much anticipated Marvel comic adaptation "Guardians of the Galaxy" opens August 1st in regular cinemas, 3D cinemas and in IMAX 3D. In regards to the latter two, Gunn has spoken about the adjustments to the film on his Facebook page:
Just got out of working on the Guardians cut for IMAX 3D and I'm unbelievably excited about it. Guardians of the Galaxy has been planned as a 3D film from its very inception. Yes, if you see the film in 2D, you'll get a full experience. But the 3D experience promises a little something extra.
Unlike many directors, I've been actively involved with converting every shot to 3D, making sure it works perfectly for the story and the film, making sure it's spectacular and immersive without being silly, distracting, or overly showy. 3D conversion was once far inferior to shooting in 3D, but over the past couple years new technology has allowed us incredible control over the 3D effects, making it equal to or in some cases greater than shooting in 3D.
As an EXTRA benefit for those who see the film in IMAX 3D, we will be changing aspect ratios throughout the film in a way that makes the experience even fuller and more encompassing. I've personally chosen all the places where the changes occur and, again, I love how it's coming along. The changing aspect ratios in this case are actually a part of the storytelling.
There's also a new TV spot out for the film, boasting lots of new footage, which you can see below:
