The oral history of the Dinosaur Input Device
vfxblog.comGreat read about two worlds coliding. Also interesting to consider the level of artistry and care, ncessitated by exteme limitations, that went into the very short sequences in Jurassic Park and how alive those dinosaurs feel... versus the more technologically unbound filmmaking for Jurassic World movies, which to me offer nothing exciting to look at.
To me the CGI dinosaurs in the original movie have still not been surpassed.
This was on the TV show Movie Magic ages and ages ago, but they certainly never went into this much depth and backstory. This is a great writeup.
Also in the more recent ‘Light and Magic’ ILM doc series.
