Lego has been around for 83 years, there are more than four billion Lego figurines in existence, and James May once built a house made entirely from the little bricks.
So it's safe to say the world loves Lego - in fact in 2013 Lego became the most profitable toymaker in the world.
Now the notoriously secretive, privately-owned superbrand is opening its doors in this documentary, introducing some of its key people and revealing more about the company DNA than ever before.
The Secret World of Lego follows Justin, a 23-year-old design student, as he travels to Lego headquarters in Denmark in pursuit of one of the most hotly contested jobs in the world, a Lego set designer.
The programme also meets Liverpudlian Matthew, who undertook the same process and has now risen to become a vice-president of design; and Mark and Tom, two adult fans of Lego, as they try two different money-making schemes they hope will transform their love of the brick into cash.
