Olive's back and this time she's playing a wicked witch in Halloween Queen.

With a movie set full of potions, spells and special effects, it should be a total fun fest (even when her co-star is the biggest bully in showbiz/Sofia La Bullybum). Every day Olive is transformed into an ugly, evil witch while her nemesis looks like an angel. Luckily, everyone knows it's what's inside that counts. Right?
