Bad news, guys. I think that the new Alice Through the Looking Glass movie has no size-changing scenes. I've just read a recent interview to Mia Wasikowska, who played Alice and look what she says.
"Do you see yourself as more of a heroine now in this movie?
WASIKOWSKA: Yeah. Alice is always saving the day, but it was nice in this. Also, in the last one, I was changing sizes a lot, which meant that I didn’t get to act with the other people very often, and in this one, I was the same size. I know that seems like a very slight technical thing, but it actually meant I got to do a lot of scenes with people pretty much always. That was really nice."
