Hey, I'm the writer of Just Before Dawn and yes I'm still around. I haven't finished/submitted any scripts for quite a while though. I was pretty surprised to find people discussing this one again! Glad you liked it, although I think my writing has improved since this script so I sort of cringe when I look back on parts of it, to me it's a little embarrassing that people are reading it now! As a result it's currently being completely over-hauled because I think I can make it much better (and I want to make it an original story rather than a re-make of an existing film).
I do have another script on here, it's a slasher called REPRISAL (currently on page 6 here in the Horror section). But again, it's old so in my opinion it's not up to scratch. It too is being over-hauled dramatically because I think I can turn out a much better script. Feel free to take a look at it but be aware that I've sort of moved on lol.

Wow.  I'm really impressed by this.  You're very faithful to the original story, but you manage to add your own style and interpretation to make it fresh and interesting.  This is a lot fun.

The highlights here are the definitely the death scenes, two of which are very effective.  While I think Kansas' is the most unexpected and original, I think Adrienne really got it rough.  I imagine if this were a film, the MPAA would have some fun ripping the crap out of that scene.  I also love the waterfall scene where it turns red without the characters noticing.

You have some fun toying with the chase scenes, which I enjoyed.  Chase scenes are always good.

The dialogue is passable, but decent for a film of its caliber.  Most of it seems like "Where is _____?  How do we ______? Where are we gonna _____?"  But this is how the average person acts when they're scared -- questions come out like diarreah of the mouth, which is ok.

Keep writing.
