Based on a true story, in rather dramatic fashion the movie features the moving of 50 tonnes of gold representing Norways reserves - worth about £3bn at todays prices. It's a measure of how well Norway has managed its economy that today, whilst not held in gold, it's reserves are worth about 20 x more at £60bn, although this hasn't kept up with inflation!
The heroes sister Lili (Ida Elise Broch) is helping them avoid leaving the gold in Lillehammer, she starred in the Netflix show about the same place, Lilyhammer!
