--------------------------------------
I am not shure how Amblin does there shock waves, but I have done a couple on
some of my animations.
I morphed a simi transparent sphere, and in one case a simi transparent
Toroid, (doughnut) with the center removed.  Make one  object small enough to
fit inside your planet or inside the blast center. Save it as shockwave. Then
copy the shockwave object and increase the size until the front of the
schockwave goes through the camera position a little bit. Kill (K key) the
polygons so all that is left are points, and save it as shockwave.target.
For surfacing, I used a faint fractial pattern with different velosities in
all directions to give it some life.
 In layout, set-up the morph to move as fast as you can. 10 or 15 frames
should work. (if your camera is lightyears away you may need to add more
frames) Use motion blur with a blur length around 75 to 85% to make things
happen smooth.  For the final touch you may want to add a astoroid or a small
ship near the camera to get blown away when the schock wave arrives. When the
shockwave  gets to the camera, give it a little shake and  dissolve out the
schockwave once its past the camera.

 I hope this helps.
