IIRC, the only new scene shot was the interior of the Mothership. (Richard Dreyfuss was brought back in to shoot his reactions during the production of 1941.) Everything else were scenes that didn't make it into the 1977 cut originally. The ironic thing is that the Special Edition is harder to see these days. Spielberg has disowned it, claiming the new ending was something the studio forced him to add before he could recut the film. (And he recut it again in the 90's!) The weird thing is the last couple times CE3K has been on TNT it's the special edition. Steven should have had the term copyrighted as it's been abused so much in the past decade!
