Gare Montparnasse in the context of "Paris Métro Line 12"

Line 4 (French pronunciation: [liɲᵊ katʁᵊ]) is one of the sixteen currently opened lines of the Paris Métro, as well as one of its three fully automated lines. It connects Porte de Clignancourt in the north of Paris, to Bagneux-Lucie Aubrac in the eponymous southern suburban city, on a north-south axis across the French Capital. Held within the boundaries of the City of Paris for over a century – until its southern terminus was changed from Porte d'Orléans to Mairie de Montrouge in 2013 – the line was sometimes referred to as the Clignancourt – Orléans Line. At 13.9 km (8.6 mi) in length, it connects with all Paris Métro lines apart from the very short 3bis and 7bis branch lines, as well as with all 5 RER train lines. It also serves three of the Paris Railway stations, Gare du Nord, Gare de l'Est, and Gare Montparnasse. It is the second-busiest Métro line after Line 1, carrying over 154 million passengers in 2004.

Line 4 was the first line to connect to the south side of the River Seine, through an underwater tunnel built between 1905 and 1907. Line 4 long ran the longest-serving MP 59 rubber trains, which used rheostats to dissipate the braking power through resistance, making line 4 the hottest line in the system. Those trains were withdrawn from service on Line 4 during the course of 2011 and 2012 after 45 years (with some being in service for 50 years), yet remained another 12 years on in service on Line 11. On Line 4, they were replaced by the MP 89 CC stock transferred from Line 1, right after its automation.

Hugo is a 2011 American adventure drama film directed and produced by Martin Scorsese, and adapted for the screen by John Logan. Based on Brian Selznick's 2007 book The Invention of Hugo Cabret, it tells the story of a boy who lives alone in the Gare Montparnasse railway station in Paris in the 1930s, only to become embroiled in a mystery surrounding his late father's automaton and the pioneering filmmaker Georges Méliès.

Hugo is Scorsese's first film shot in 3D, about which the filmmaker remarked, "I found 3D to be really interesting, because the actors were more upfront emotionally. Their slightest move, their slightest intention is picked up much more precisely." The film was released in the United States on November 23, 2011.

The 14th arrondissement of Paris (French: XIV arrondissement [katɔʁzjɛm aʁɔ̃dismɑ̃]), officially named arrondissement de l'Observatoire (IPA: [aʁɔ̃dismɑ̃ də lɔpsɛʁvatwaʁ]; meaning "arrondissement of the Observatory"; named after the Paris Observatory), is one of the 20 arrondissements of Paris, the capital city of France.

It is situated on the left bank of the River Seine, containing most of the Montparnasse district. Although today Montparnasse is best known for its skyscraper, Tour Montparnasse, as well as its major railway terminus, Gare Montparnasse, both are only partially located in the neighbouring 15th arrondissement. The district has traditionally been home to many artists as well as a significant Breton community, which arrived at the beginning of the 20th century upon the creation of the Montparnasse railway terminus.

The 15th arrondissement of Paris (French: XV arrondissement) is one of the 20 arrondissements of the capital city of France. In spoken French, it is referred to as le quinzième ('the fifteenth').

The 15th arrondissement, called Vaugirard, is situated on the left bank of the River Seine. Sharing the Montparnasse district with the 6th and 14th arrondissements, it is the city's most populous arrondissement, with a population of 229,472 as of 2020. Tour Montparnasse – the tallest skyscraper in Paris – and the neighbouring Gare Montparnasse are both located in the 15th arrondissement, at its border with the 14th.
