I thought the pre-production/visulisation work for Jurassic Park was done on Amigas. As for ST:TNG, I wasn't aware they used Amigas... but as a fan of Star Trek, it would make me happy if they had.
The real question is... how many of those companies STILL use Amigas? Babylon 5 (and Seaquest 20302???) went over to PCs soon after Lightwave was ported.
