YOU SHALL NOT PASS!
Sir Ian McKellen doesn't seem to bothered continually repeating one of his most famous lines, as students in Bristol found out when he unleashed his inner Gandalf.
The veteran wizard gave some magical advice to the students on what would happen if they don't revise properly.
He asked them, "In your preparation for your examinations, if you don’t do your revision properly, do you know what will happen?" The students replied, "What will happen?" That's when Ian McKellen became a million times cooler.
