Sir Ian McKellen has offered school-children exam advice in 'Gandalf' style at Chew Valley School in Bristol.
The 75-year-old actor asked the kids whether they knew what would happen if they didn't revise properly in their preparation for the examinations, the Mirror reported.
The 'Lord Of The Rings' star then shouted out "You shall not pass!" in the classic Gandalf fashion, which was followed by cheers and clapping from the youngsters.
