Mithrandir, you can't just add a "tremblor" as you call it without reshooting the scene with a breeze blowing. Besides, the scene is just fine as it already is.

I agree, the scene is just fine as it is. You don't need realism in every shot. Thats what current hollywood is so hung up on.

That scene is a crucial part of the story, and you don't need wind in the face just to sell the effect that luke is flying away in his x-wing at the same time yoda is talking to Obi-wan. Lighting, music and sound FX are all that is needed.
