Honestly, I have been completley unaware of this debate regarding Kath Soucie's date of birth and you're the first one to actually mention to me.
You see, when I google her, her date of birth pops up and reads November 18, 1953. I also looked at celebreties born today on ImDb and Kath Soucie is listed as one of them. But I've been told that google and imdb are not reliable sources.
I don't know, and there probably aren't any. There is also the possibility that Kath Soucie chose not to go public with her birthday. Remember, some celebrities like to keep personal things to themselves.
ADR means "Automated Dialogue Replacement". Basically, it's when an actor or actors are called into a recording studio to either add background dialogue to a scene in a TV show or movie, or to record over an actor's lines in a TV show or movie to refine it and make it able to be heard by the audience. Here's an example of Hugh Jackman doing ADR for the movie Logan: https://www.youtube.com/watch?v=DyS5agWSIrY
It can also help when you think about it as the process through which many Japanese video games and anime get English language releases; voice actors are called in to record, or "dub", over the Japanese video to an English script.
