Some characters from the CATS film are dubbed. Who & Why?

Jemima - Veerle Casteleyn's dubbed trough the full musical, by Helen Massey/Helen Massie, because she's from belgium and her accent was too heavy. But they wanted to have her in the film, because she was so cute and had such a "wide-open face".

Skimbleshanks - Skimble was dubbed during his song by David Arneil, because Skimble had a scottish accent - and Geoffrey not. His other parts were sung by Geoffrey Garrat  himself.

Mungojerrie and Rumpelteazer - They were just dubbed trough the beginning of their song (The giggling and the "Sssh") by Paul Baker and Vicky Coote.
