'A real life horror film': Terrified viewers watch from edge of their seats as SNAKES hunting as a pack chase down baby iguana in amazing footage for BBC's Planet Earth II that even shocked Sir David Attenborough

We were literally cheering on the Iguana's, amazingly they seemed to know they were in danger the minute they emerged...... those snakes were incredible though, who every thought snakes hunted in packs? The teams involved in these landmark series deserve recognition, they have brought so much knowledge and awe to our small screens.

Excellent TV! What a start to the new series, long live Sir David A !

Everyone in our house was shouting at the iguanas . 'Don't come out yet! Run iggy run, especially the iguana that ran, was caught by the snakes and managed to escape. We were cheering him on.

Wonderful informative and astonishing.Best BBC viewing in ages.

I think its the first time I have cheered and Iguana, I was relieved when he eventually got to safety.

It was a classic BBC wildlife scene, really nailbiting edge of the seat stuff. Well done BBC on the dedication, patience and talent that goes into capturing such scenes.

One word FANTASTIC !!

Amazing tv. Well done to Sir David and his team.

The snakes were fascinating, never imagined they could move at such speed. We were shouting at the iguanas to run faster. A brilliant programme, can't wait for the next one.

The worlds wildlife still amazes me

Incredible filming and editing. The producer, director and cameramen who are involved in these programmes should be properly acknowledged and awarded. Truly spectacular and nail biting. Great show, cant wait for next week.

TV doesn't get much better than this. Incredible filming.
