What part of script-writing do you need help with?
If you are looking for templates so you can write it with it LOOKING like a full cool hollywood script, check out these:
http://www.bbc.co.uk/writersroom/scriptsmart/
this has word templates (make sure you read, theres a special second template down the bottom, and instructions on how to make it work, as well as several good articles on script writing technique.
The second is a program called CeltX
http://www.celtx.com/
This program is quite rocking. It has a script writing utility that lets you write a script like a pro. It has several tabs where you can write character bios with designated spaces for pictures, sections on physical characteristics, character motivations etc...looks great in your journal visually and makes your ideas clearer to yourself. Also the best part is it hosts a functionality that you can share your scripts with ppl around the world for reviewing purposes who also have the program (And get an idea by reading from others). The only problem with this (as i have found, im currently using it to write the draft script for my radio drama) is that its relaly hard to transport into Word to email it to people.
