I'm reasonably fluent in Afrikaans, and I've tried translating short pieces into English. It's not easy. (Afrikaans is similar to Dutch.)
I think translation means writing what the author would have written if his home language were English. That meant understanding the piece in all its nuances of meanings as well as the author did, and expressing it in language at a similar level (formal/informal, educated/plain-spoken etc.)
As to writing down something already pre-existing in the ether; nope. Maybe something short, like a pop song or jingle. I have the image of chipping away the unwanted notes to reveal the melody like dinosaur bones embedded in rock. But bigger pieces like screenplays I believe can only be painfully assembled and glued together with sweat and blood.
