Where can I find a Word screenplay template asap?

I've used CelteX. I'm not sure if this does all you want but you can get a free trial version. Here's a review.
“What’s the best of the cheapest or free screenwriting software?”
The answer to that question can come in many colors, depending on who you ask, but one particular screenwriting suite that was the savior of many a wealth-challenged screenwriter within the last decade was the aforementioned CeltX, the free screenwriting software that, as I mentioned, has recently gone the way of the “cloud,” phasing out their desktop/downloadable/installable version.
CeltX has been called “a flexible “full-fledged preproduction software package,” and includes writing templates for film, tv, and virtually any other format you can think of. As a piece of desktop software, it spanned the gap between new screenwriters having to use clunky Microsoft Word templates or forking over $250+ for Final Draft or a similar “big name” screenwriting program.
Here’s their website:

If you do a google search you can still find a free download which is what I did.
