CAVEMAN Grug Crood (voiced by Nicolas Cage) has taught his family to be afraid of the dark and new experiences.

He protects his wife Ugga (Catherine Keener), restless daughter Eep (Emma Stone), oafish son Thug (Clark Duke), feral baby daughter Sandy and decrepit mother (Cloris Leachman) by ushering them into a cave, where they will be safe from the prehistoric creatures that roam the land.

Eep dares to rebel, and during a forbidden night-time excursion she encounters a nomadic caveboy called Guy (Ryan Reynolds), who tells her that the end of the world is nigh.

Soon after, the Croods’ cave is destroyed by a massive earthquake that heralds the disintegration of the landmass into continents.

The Croods join Guy and his pet sloth Belt on the expedition through uncharted territory in search of a new place to call home. En route, Grug confronts his fears about losing his children and Eep fans the flames of romance with Guy.

The Croods is inoffensive, effervescent family fun that strikes a pleasing balance between romance and adventure. Each member of the titular family has distinct personality traits and writer-directors Kirk De Micco and Chris Sanders construct a nice running gag about Grug wishing his mother would shift her mortal coil.

This film bursts with vibrant colour, especially in eye-popping 3D, available exclusively on Blu-ray.
