Miss Peregrine's Home for Peculiar Children film

Saw a trailer for this and one scene in particular caught my eye.  Apparently, one of these peculiar children is a girl who is lighter than air and can manipulate it (also, she's listed as a teenager and her actor is almost twenty, so I don't think they mean a literal child).  Doubt we'll get that lucky, but it's certainly good inspiration material.

(Scene that got my attention is at 1:35).
