Various websites say "The Sword in the Stone (1963) UK DVD" omits the following:
I also read on a disney-wiki somewhere, this edited line version might be used on Disney+ (if that is at all relevant).Part of Madam Mim's first line "Sounds like someone's sick. How lovely. I do hope it's serious. Something dreadful." She now says "Sounds like someone's sick. How lovely."
There is no mention of this edit on the "The Sword in the Stone (1963)" DVD page here on dvdcompare.
There are x2 UK DVD releases listed here on dvdcompare - based on moviecensorship comparison, it looks like this line is specifically edited on the UK 45th Anniversary Edition. (Unknown if the earlier UK 2002 DVD release is affected or not)
