Everyone’s gotta start somewhere. Even the most celebrated films started as half-baked rough drafts. Who knows, maybe that crumpled up screenplay at the bottom of your trashcan is the next cinematic masterpiece. Probably not, but maybe? These totally real rough drafts successfully made the jump from steaming pile of dog shit to hollywood blockbuster.

1. The Wizard of Oz

As far as films go, The Wizard of Oz set the bar very high, very early on. It changed cinema as we know it. But we got our hands on its earliest draft, and let’s just say - it wasn’t always so great (or G-rated).

2. The Godfather

Ask any movie buff to list the greatest movies of all time and without a doubt, The Godfather lands in the top ten. Mario Puzo helped to adapt the screenplay from his own book, but it seems like he didn’t really understand how to write for film.

3. Jaws

Steven Spielberg has given us classic after classic. E.T., Jurassic Park, Saving Private Ryan – all masterpieces. His first directorial masterpiece, Jaws, put him on the map. The movie redefined the horror flick, but it seems like the screenwriter had something else in mind when he started writing.

4. The Sixth Sense

M. Night Shyamalan’s The Sixth Sense is known for its twist ending. But apparently it took a few rewrites to flesh out that iconic last scene.

5. The Avengers

Today’s all about the blockbuster. Movies rake in billions of dollars at the box office. Bigger names, bigger explosions and most importantly, bigger budgets. It might just be me, but it looks like the folks over at Marvel Studios were a little dependent on that sweet product placement cash early on in the writing process.
