The Croods has debuted a new poster, Digital Spy said.

DreamWorks Animation has invited the public to "meet the first modern family" with its latest artwork.

"Are you better off than you were four million years ago?" asks the poster.

The film centres around a prehistoric family whose father terrifies them into never leaving the cave that is their home.

When a landslide buries the cave, the Croods are forced to go out and explore the beauty and dangers of the outside world.

Emma Stone, Nicolas Cage, Ryan Reynolds, Catherine Keener, Clark Duke and Cloris Leachman have lent their voices to the film.

The film was written and directed by Chris Sanders and Kirk DeMicco.

The Croods will debut in UK and US cinemas on March 22.
