used were for sequences depicting the lassoing tongue of a chameleon (which had to be filmed at ultra-high speed) and the digestive system of a python (which was enhanced by computer-generated imagery). Life in Cold Blood is Attenborough's last major series and also represents the final study in his 'Life' series, which comprises 79 programmes. In a 2008 interview, he stated: The evolutionary history is finished. The endeavour is complete. If you'd asked me 20 years ago whether we'd be attempting such a mammoth task, I'd have said 'Don't be ridiculous'. These programmes tell a particular story and I'm sure others will come along and tell it much better than I did, but I do hope that if people watch it in 50 years' time, it will still have something to say about the world we live in. However, although Attenborough was 81 years old at the time of the series' broadcast, he continued to assist the BBC Natural History Unit by providing narration for projects such as Nature's Great Events, Life and Frozen Planet. Attenborough confirmed on the penultimate edition of Parkinson, broadcast on 16 December 2007, that he did not intend to retire completely and would still make occasional single documentaries, rather than any more series. Episodes DVD and book A 2-disc DVD set of the series (BBCDVD2553) was released on 25 February 2008. The accompanying 288-page book, Life in Cold Blood by David Attenborough (), was published by BBC Books on 7 December 2007, in advance of the television series. The Region 1 DVD was released on 5 August 2008 (S.R.P. $34.98) through Warner Home Video.
