Ever wondered about life in caveman times?
Even if you haven't, your children may be enlightened by this animated family's primitive journey through times of dinosaurs and prehistoric creatures.
Though lifestyles have moved along since those basic times, the overarching theme of a father wanting to protect his family at all costs is still relevant today in our sophisticated world.
Grug (voiced by Nicolas Cage) is a simple guy - his mantra is the cave is your friend and always stick to the rules.
He allows his family out briefly during the day to catch some food, but the rules say it is then straight back to the cave and the safety it offers.
