By the way, I’ve discovered that the IMAX picture found here (http://media.washtimes.com.s3.amazonaws.com/media/image/2015/12/16/film_review-the_force_awakens.jpeg) - that is 1.33:1, by the way - has been recomposited (unless BD/HDTV were recomposited instead, but I don’t think it’s the case)

Yeah, the promotional still is a Photoshop of several different frames, so that you can have both Rey and Finn in good poses plus a good explosion, plus the tie fighter firing all in one image.

This is the frame Rey and the left half of the image are taken from (as you can see, Finn’s pose is not as dynamic and too blurry):

BB-8 and the tie fighter are from different frames as well.
