Lysette Anthony's voice was dubbed by Lindsay Crouse (From Iceman 1984 fame) In order to make her character sound more American to boost ticket sales.
Robbie Coltrane's voice was also dubbed, by English actor Michael Elphick. However Mr Coltrane was born in Scotland and Elphick is just about as British as they come so the reason for that escapes me.
[ED's Note: An English accent is a probably lot easier for Americans to understand than a Scottish one!]
