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?
