Planet Earth was first broadcast in the United Kingdom on BBC One in March 2006, and premiered one year later in the USA on the Discovery Channel. By June 2007, it had been shown in 130 countries worldwide. The original BBC version was narrated by David Attenborough and produced by Alastair Fothergill. For Discovery, the executive producer was Maureen Lemire, with Sigourney Weaver’s voiceover replacing Attenborough.
The series comprises eleven episodes, each of which features a global overview of a different habitat on Earth. At the end of each fifty-minute episode, a ten-minute featurette takes a behind-the-scenes look at the challenges of filming the series.
