Sir Ian McKellen, who plays Gandalf in the Lord of the Rings movies, gave some exam advice to pupils whilst on a visit to a school near Bristol.

The words were actually lifted from his Lord of the Rings character Gandalf...

Yep, you guessed it!

Speaking to a group of excited students, McKellen asked: "If you don't do your revision properly do you know what will happen?"

Before bellowing, "You. Shall. Not. Pass!"
