Yeah, it made heavy use of CG. I can't be bothered to look it up, but I am sure it came out mid to late nineties. I think I remember seeing posters for it in theaters around that time. Definitely wasn't an 80's film, they didn't have awesome CG special effects like that back then.
If they'd tried to make something like that in the 70's or 80's it would have looked like shite.
