Yes, here in America it is called 'The Sorcerers Stone'
I have no idea why they changed it.
I think it's rather silly to change certain words in the British and American versions. I would like to read it as it should be, not some changed version.
Well, I guess they changed it because here, a Philosopher and Sorcerer are two completely different things. Maybe they are there too....I don't know.
Ah, I'm confused
But anyway, yea...I guess they said Sorcerers Stone in the movie because there are more Americans than there are Britains.
