Help, I Shrunk My Parents (2018)

Schoolboy Felix Vorndran is inconsolable when his parents decide to move to Dubai for father Peter's dream job. His dream wish once more comes true, with undesirable consequences. The haunted school's janitor-sorcerer Otto Leonhard both shrinks his parents, who now totally depend on him, and allow evil former principal Hulda Stechbarth to come to life and impose a rule on terror, although modern pupils don't just submit. Only tireless Felix can fix it all, with some help.
