Land Rover is celebrating its 70th anniversary this year, but it wants to remind us it's still a brand with an adventurous spirit.

To mark the milestone, agency Spark44 has made an ad which doesn't have a car in sight, but instead a series of children running around and playing outdoors remind us what it is to be young. In particular they accuse adults of growing up to be boring: "All you do is work, and do groceries, and talk about the economy."

Production company You are Here and director Joe Connor made the film using non-actor children from all over the world (including locations such as Bulgaria and Nepal) and as a result there's a nice authenticity to the kids' urgings.

The spot concludes with the line: "We've all got to grow up... but it doesn't mean we have to grow old inside." It's running on TV and online, with the message that Land Rover is "70 Years Young."
