Oh, yeah! Two years ago, I read a script about a farmer. Part of a script. It was clear on page 2 that the writer hadn't the faintest clue about tractors and how they're maintained, operated and shared. There was no point in reading further. Despite some excellent writing, the entire story depended on the (imaginary) tractors.
Of course, not every script requires lengthy advance work; it depends on the world being described.
I tend to write just a little ahead of my research in places, dropping in "zxc" to flag a guess. (It's heartening to occasionally find I've guessed right.)
Yes, research slows the writing and can become procrastination. I believe it must do those things to some degree, if done correctly. It's a matter of balance. I've concluded that the only way to know I've researched too long is AFTER I've already done so. I can only try to stop as soon as feasible.
But the bigger danger, for me, is not excess research, but the tendency to cram ALL those really nifty facts into my script. I have to reserve the excess for the novel.
