Did Shakespeare really write Shakespeare - or not?

Most of us have learned about world-famous poet and playwright William Shakespeare at school - or from Horrible Histories!

But a new film out now suggests that Shakespeare himself may be FAKE history.

The movie Anonymous is about how the most famous plays on the planet might have actually been written by someone else.

It's not a new idea, but the suggestion has really angered some Shakespeare fans, as Joe's been finding out.
