Known for its fabulous airline safety videos, including one featuring hobbits, Air New Zealand has just pulled another one out of the bag. This time, it's an Antarctic-themed film, starring "Entourage" actor, director and UN environment ambassador Adrian Grenier.

The so-called "World's Coolest Safety Video" sees Grenier travel to the Antarctic with a team of scientists and six Air New Zealand crew members (a deliberately small team in order to minimise the environmental impact of filming.) There are penguins, seals ice cliffs and inside views of explorer Ernest Shackleton's hut as we're talked through the usual safety instructions. Meanwhile, 22 schoolchildren aged eight to 11 also play a starring role, appearing in footage shot in Canterbury Museum's Antarctic Gallery and speaking to Grenier by video link. See the Behind the Scenes film for more on how it was done.

As well as making a entertaining film for passengers to watch, the film, created by New Zealand agency True, is intended to shine a light on climate change and the work of New Zealand scientists in the Antarctic.

However, some reports from New Zealand describe the video as "controversial." The reason? An Air New Zealand flight crashed into Mt. Erebus in the Antarctic in 1979, killing everyone on board--and some of the families of those killed are disturbed at the airline associating itself with the area. Air New Zealand has apparently told media that it didn't feature Mt. Erebus in the video, out of respect for the families, but some are still upset that it focused on the Antarctic.
