Yeah, I never had much of a problem with the design of the rancor as much of the model, well, puppet that they used. Its plenty scary if the lighting is right, as Angel's mockups showed!

And of course more ILM lying about the mattelines: they said they'd removed them in the SEs but they weren't removed until the 2004 DVD. One less thing that need fixing by Adywan I suppose.

First, ILM doesn't dictate what is done and not done. That's the director's or filmmaker's prerogative. Second, ILM never said they'd fix matte lines on everything. Basically, if Lucas didn't budget for it, it didn't get done.

There's this idea out there that fx companies can almost do what they want with a film. They're service companies under contract by studios or production companies to do specific things.

Unless it's an ILM production(coming soon with Gore Verbinski's Rango) or co-production(there were some of those in the mid-'80's), they don't have the kind of control you're speaking of.
