It's Gandalf the GREY, not GRAY!
Also, as mentioned Gandalf falls straight down without holding onto the ledge in the books. From which, when I first read the books MANY years ago was devastated. Although I should have realised he can take care of himself, I did not realise this as I had not read any of the companion info such as History of Middle Earth Vol 1-3 and Silmarillion and the Hobbit.
I was quite young as well, was proud of readin LOTR when I came to read the Hobbit and realised how much more simple in terms of the use of the English Language is compared to LOTR. Anyway, enough babbling 🙂
