So there is a Disney direct to DVD film called "Balloon Farm" and it is one of those Mara Wilson films to boot (and one where she is too old to use charm to sell copies XD). I bet its a weird film, but I want a little insight. No inflation scenes officially confirmed, but hey, it could be something to look at in case it does.
There's no inflation in it that I remember. But I only watched it once.
