I would imagine this will be available on Blu-ray sometime soon. My experience from watching it in the theatre last night is the conversion to 3-D of this movie works just as well and better than the conversion of Star Wars: Episode 1. There was natural roundness to everything just like in the 3-D Star Wars movie, however in Jurassic Park, there were seemed to be much more foreground information; almost as if the movie itself was deigned to be 3-D from the start!
On the down side, there were two (quick) scenes I could see the digital artists had some trouble with the conversion. One only had to do with artistic capability of rounding a forehead. The other, a vehicle that should have been behind a plant was both in behind and even with the plant (due to it's moving vehicle blind shade effects.) It's hard to describe, but it only lasted about one or two seconds.
I checked out the origanal trailer of the movie and I saw two scenes I don't remember seeing in the film.
1. When Laura Dern grabbed the leaf from the moving vehicle. We see her looking at it in the movie saying it was impossible to be living. But we never see her grab it like shown in the trailer. Actually, that's the way I remember it from 20 years ago! For what ever reason, I think it was simply cut from the movie OR I simply don't remember seeing that in the movie.
2. The water wave in the small plastic cup scene. I might have missed it, but I don't remember seeing the water wave in the cup (due to the dinosaur steps.)
In the movie I saw last night, I remember seeing the water wave outside in a puddle, but I don't remember the water wave in the small cup. I don't think that would have been cut out of the movie, I must have glanced down or been eating popcorn during that quick scene.
