"Harry Potter and the Philosopher's Sorcerer's Stone"

"Sorcerer" sounds exciting, "philosopher" sounds boring, and nobody in America knows what a philosopher is. Famous title changes to take account of the incredible ignorance of the average American include "Licence Revoked" which became "Licence to Kill" when over 70% of those polled didn't know what "Revoked" means, and "The Madness of King George III", which had to drop the "III" because it was realised that Americans would be uninterested in the film since they'd obviously missed the first two films of the trilogy.
