Terri Hawkes was Sailor Moon in all the movies. There were two versions of the dubs for those (edited and uncut), but the voice work was unchanged. In the uncut dubs, the Japanese music was retained. In the edited versions, it was swapped with DiC music alongside the cuts. Those were the only differences.
Linda Ballantyne was only Sailor Moon in the S/SuperS seasons. Toby Proctor was Tuxedo Mask in MOST of Classic (after the Jedite arc), and the first 2/3 of R (until the Weird Sisters are defeated).
Linda Ballantyne was never Sailor Moon in any of the movies. In all existing movie dubs, it's Terri Hawkes. YTV in Canada showed the same dubs as Cartoon Network in the US. There was no reason for them to produce second dubs of any of them. Yeah, there was the edited and uncut versions, but the actual voice work was identical between them.
The movies were actually the final time Terri Hawkes voiced Sailor Moon. She did kinda sound like Linda in the end there though.
Really? That's so hard to believe. There's no doubt in my mind you talked to her manager (Do you have confirmation they were real?) but you have to admit, the similarities between Princess Kaguya and Mimet are uncanny.
