If any change was to be made, my vote would be to have the spider standing still for the first few moments, looking like a rooted plant, then become more animated as the shot progresses. (from McQuarries paintings, that's how I always imagined they'd have been introduced in the film)

I like this idea. They do this effectively a few times in The Dark Crystal.

Glad ya like it.

All the other ideas to change this shot seem overly complicated.
The main reason I made this suggestion is because based on the creature design and the original artwork, I always figured it was meant to seem like a strange plant before it starts moving.
It standing still a bit also goes with Monroville's idea that the crash would startle the creatures. The spider has no reason to run though when it can just stand still and hide (also, based on the large size of that thing, I get the impression it's not scared by much). Once the shock of the crash fades, the spider goes back to doing what it was doing.
