I've been working on a screenplay, and I thought I'd share a resource I've found.
Screenplays require special formatting. One option is to buy screenwriting software such as "Final Draft." (I recommend against "Hollywood Screenwriter," for reasons I won't go into now.)
However, if you're not ready to spend the $190 or so for dedicated screenwriting software, here's an alternative I've found useful: "
ScreenPro." ScreenPro is a screenwriting template for Microsoft Word. Basically, it adds all the proper formatting as "styles" in Word. It has buttons you can push to choose between the character name style, the dialogue style, the action style, etc. It also tries to guess what the next style should be (i.e., if you've just done the character name, the next line is probably dialogue), and if it's wrong you can use the tab key to cycle through styles to find the one you want.
ScreenPro is shareware, which means you can test it out for free. If you like it, registration is only $8.50.
