Ever wondering why your beloved cat is obsessed with catnip and silver vine? It’s widely known that cats rub their heads and faces on the plants and roll all over the ground, as if the plants had put a spell on them.

The new British series Alien Worlds narrated by Sophie Okonedo is a blend of sci-fi and documentary. By applying the laws governing life and basic physics and chemistry on Earth, four imaginary exoplanets (planets orbiting stars outside the solar system) with different aliens living on them are conceived and presented using beautiful computer-generated imagery (CGI) animation.
