Better get to work on it, right?
No! Of course you don't make a summer blockbuster, you've got no money or experience, how can you? Instead, make an indie movie. Show off what you can do with little resources; get yourself on the map; let the little indie movie shine; attract producers who give you a budget to do something a bit more adventurous. Maybe then you make your summer blockbuster.
You don't just try and make a summer blockbuster with no money you stupid fucking twat!
