I got to this terrific place because, like Goose said in Top Gun - I was stupid.
I signed with The Screenplay Agency. Then when I told some of my writing buddies out here in L.A. about it, they said Hey! Lookie here! They're body-slamming that Screenplay Agency around the block and halfway to the moon! Read 'em up, boy!
So I did, and was impressed with how helpful people here were, in their posts. I just lurked and read, too afraid (then) to admit that at my old age of 49 - I'd been taken. You think you'd learn.
My new strategy is to send one word (numbered) of my script to every single agency I can think of. They call each other up, put the words together in the proper order, print the thing out and somebody buys it! Piece o' cake...
