@slurpeez108: I’m putting my money on Oz. Primarily because the door looks like curtains, which is central in the story because of the ‘pay no attention to the man behind the curtain’ line near the end. ( Also thanks for the screen-shot. I’m noticing some patterns on the floor outside what I’d initially mentioned. Hm… )
@Mia: I kept wondering about that one. My initial thought for some reason dealt with Valentine’s Day – however I now submit to your idea/theory in regards to that door. Looks oriental & could very well be Mulan.
@Sjm: Lol I might be Regina’s reflection yes but perhaps it really is a Chimney, as a sort of nod to Mary Poppins perhaps? If it is Regina’s reflection though, then does that mean there is another mirror directly behind the looking glass? I mean, based on slurpeez screen-caps I saw there was another door that had a mirror on it – but it wasn’t full length & it would have to be to cast her full reflection.
Another world would/could be Atlantica ( the Little Mermaid ) although, a part of me would want them to have to go through water to get there. So none of these doors directly correlate, at least, I don’t think so.
