Former England football captain David Beckham talks about his new documentary which sees him journey into the heart of the Amazon rainforest.

Beckham travelled with three friends to Rio de Janeiro and then on to the rainforest as part of the 90 minute film.

The footballer who hung up his boots last year described the experience as 'humbling' and at times 'terrifying'.

The documentary, David Beckham: Into The Unknown will be broadcast on Monday 9th June, at 8.30pm on BBC One.
