The Times BFI 51st London Film Festival is proud to welcome Kyoto Planet as host of the gala screening of Into the Wild on October 25. Kyoto Planet, a company dedicated to creating meaningful solutions for an eco-friendly future, firmly believes that big changes can come about when everyone participates — and film is a powerful medium for sharing that belief.

Into the Wild, directed by Sean Penn, tells the true story of Christopher McCandless, who abandoned his material possessions and travelled across America experiencing at first hand the fragile balance between man and nature. This powerful film offers a timely reminder of the care that we need to take in our relationship with the planet.

Win our competition and you could join the growing band of people committed to a more eco-friendly lifestyle. The Toyota Prius is a fuel-efficient, low-emission hybrid, so driving one reduces the impact of your car travel on the environment.
