Two films exist with this title. (Perhaps more.) The latest - starring Isabelle Huppert - has been described as a "rather beautiful eco parable from Ursula Meier." I hope to see it one day, but this seems unlikely to be at our Cheltenham Cineworld.
Meanwhile, I've been watching the other (current) Home - at home, on the computer. It's a 93-minute documentary film by Yann Arthus-Bertrand, with the most beautiful photography of our world from the air. It also has the most annoying soundtrack, but that is easily eliminated by turning the volume off and the subtitles on. Well worth watching!
