Emily, the first whale to be tagged as part of the love earth project, had a one-year-old calf in tow.

The youngest of the polar bears collared by our scientific partners was christened Nuka - a Greenlandic term for 'younger sister'.

The third elephant collared for love earth was named Letastsi, meaning 'sun', to match her vibrant personality.

Get behind the scenes with our roving producer Jonny.

Watch the trailer and find out about the making of the film - in UK cinemas from 16 November.
