When I was a child I fell asleep with this movie playing in the tv in front of me. I literally dreamt the whole movie as if I was alice. It was such a nightmare. I was never really able to watch this movie again it was such a freak show nightmare.
Even if this Cheshire Cat in this version is far, far too mean spirited- it's hard to imagine the impact it had on the iconography- the Cheshire Cat in previous versions would just vanish and reappear with the remaining grin and head being what was unique. This one is essentially a reality warper in an odd yet mostly grounded world- capable of altering his body in unexpected ways.
