Luxembourg is one of the smallest territories in the world, ranking 167th between Samoa (166th) and Reunion (168th), but larger than 169th-ranking Hong Kong. The country measures just 82km long (maximum distance from north to south) by 51.5km wide (maximum distance from east to west). Nowhere in Luxembourg is more than an hour's drive away from Belgium, France or Germany. Luxembourg's small population has the highest proportion of inhabitants with foreign passports among all 25 countries of the EU. Luxembourg has more Michelin-starred restaurants per square mile (or per head of inhabitant) than any other country in the world. There are now no less than nine one-star Michelin and two two-star Michelin restaurants in Luxembourg. Grand Duke Jean, the father of Luxembourg's current Head of State, Grand Duke Henri, actively participated in the D-Day landings, re-enacted on the big screen in Steven Spielberg's Saving Private Ryan. Grand Duke Henri, at the age of 50, is today's youngest European monarch. Luxembourg is the world's eighth largest banking centre. Government ministers list their direct lines in the local telephone directory. Karl Marx, born in the German town of Trier, 13km from the Luxembourg border, was partly inspired to develop his revolutionary ideas after observing the abject poverty of the Luxembourg winegrowers of the mid-19th century. The most outstanding performance by a Luxembourg sportsman was in 1952, when runner Josy Barthel won the gold medal in the 1,500 metres event at the Helsinki Olympic Games. The 1997 movie American Werewolf in Paris (a critical and box-office bomb) was filmed partly in Luxembourg, as was 2001's Shadow of the Vampire (rather more successful) and 2003's critically acclaimed The Girl with a Pearl Earring.
