All Creatures Great and Small are bounding onto the big screen, courtesy of Wanted writers Michael Brandt and Derek Haas.

The new movie is set in a world where animals control the planet. Not related in any way to the James Herriot vet series, All Creatures... is described by Brandt as "a big, fun, fantastic Jurassic Park-type movie".

According to Brandt, "Because of people's inability to quench their thirst for oil and consumption of resources, we basically ruin the planet, and the planet fights back. And part of that is the quick evolution of many of the animals."

The movie takes place in a North America "where people are literally living in forts, and the animals are running free... Lions and bears and animals like that have all evolved, and they're slowly eating away at the human population."

All Creatures... will be produced by Neal Moritz for Sony.
