I wasn’t aware that Spielberg doesn’t like to release extended footage for his movies given that he has released extended cuts (or at least included deleted scenes on the dvds) for ET, Close Encounters and the Lost World. I wonder if it is just this movie he has an issue with…
Maybe. Jurassic Park is one of the few Spielberg films that has consistently gotten incorrect home video versions released with framing and colour timing different from the original 35mm projection. The colour issue is the most obvious. Even Lost World looks much better comparatively. so, who knows why JP does not get the royal treatment it deserves, seeing that it has become a beloved modern classic.
