Pretty much anywhere you go, whoever you talk to, if they know only one thing about any play by Shakespeare, it’s the balcony scene from Romeo and Juliet. It’s possibly the most famous scene ever written.
There’s just one problem with that: there was no balcony.
In the script, the stage direction is clear: JULIET appears above at a window.
Not a balcony. A window.
You can read the entire scene and see that not once is a balcony mentioned.
I don’t know who invented it, but it was a killer idea that I bet Shakespeare would wish he had thought of, were he still alive today.
Of course, directors can stage a play however they like, and make use of whatever structures, sets and furniture is available to them.
Filmmakers can do likewise, but one must keep in mind their tendency to just change whatever they want. Hollywood is notorious for that. The mayhem that comes from mass misunderstanding occurs when directors think they know better than the author, and when people watch a movie instead of reading the book.
It makes people and their assumptions about the original text wrong, and leaves them marinating in their wrongness until their wrongness is so commonly accepted that most people think it’s right.
It just goes to show that what your English teacher always said is true: there really is no substitute for reading the book.
