Pas-de-Calais (French pronunciation: [pɑ d(ə) kalɛ]) is a department in northern France. Its name is the French equivalent of the Strait of Dover, which it borders.

Inhabited since prehistoric times, the Pas-de-Calais region was populated in turn by the Celtic Belgae, the Romans, the Germanic Franks and the Alemanni. During the fourth and fifth centuries, the Roman practice of coopting Germanic tribes to provide military and defense services along the route from Boulogne to Cologne created a Germanic-Romance linguistic border in the region that persisted until the eighth century.

Saxon colonization into the region from the fifth to the eighth centuries likely extended the linguistic border somewhat south and west so that by the ninth century most inhabitants north of the line between Béthune and Berck spoke a dialect of Middle Dutch, while the inhabitants to the south spoke Picard, a variety of Romance dialects.

This linguistic border is still evident today in the toponyms and patronyms of the region. Beginning in the ninth century, the linguistic border began a steady move to north and the east, and by the end of the 15th century Romance dialects had completely displaced those of Dutch.

Calais (/ˈkæleɪ/ CAL-ay, traditionally /ˈkælɨs/; French pronunciation: [ka'lɛ]; Dutch: Kales) is a town and major ferry port in Northern France in the department of Pas-de-Calais, of which it is a sub-prefecture. Although Calais is by far the largest city in Pas-de-Calais, the department's capital is its third-largest city of Arras. The population of the metropolitan area at the 1999 census was 125,584. Calais overlooks the Strait of Dover, the narrowest point in the English Channel, which is only 34 km (21 mi) wide here, and is the closest French town to England. The White Cliffs of Dover can easily be seen on a clear day from Calais. Calais is a major port for ferries between France and England, and since 1994 the Channel Tunnel has linked to nearby Coquelles from Folkestone by rail.

Due to its position, Calais since the Middle Ages has been a major port and a very important centre for transport and trading with England. It was annexed by Edward III of England in 1347 and grew into a thriving centre for wool production and Calais was a territorial possession of England until its capture by France in 1558. The town came to be called the "brightest jewel in the English crown" owing to its great importance as the gateway for the tin, lead, lace and wool trades (or "staples"). In 1805 it was a staging area for Napoleon's troops for several months during his planned invasion of the United Kingdom. The town was virtually razed to the ground during World War II, when in May 1940, it was a strategic bombing target of the invading German forces who took the town during the Siege of Calais. During World War II, the Germans built massive bunkers along the coast in preparation for launching missiles on England.

Dany Boon (French pronunciation: [dani bun]; born Daniel Hamidou; 26 June 1966) is a French comedian who has acted both on the stage and the screen. He takes his stage name from the television show Daniel Boone.

Dany Boon, born to an Algerian Kabyle father and a French mother from the north of the country， first started his career dubbing cartoons and performing as a mime in the street. In 1992, he was given his first chance as a comedian by French television personality Patrick Sébastien, who invited him on his show. From then on Boon began to achieve notoriety with his sketches and his one-man shows.

He was then offered several roles in movies, notably in the film Joyeux Noël that made it on the international scene in 2005.

Boon is deeply attached to his native region, Nord-Pas-de-Calais. In 2003, he made a whole show in the local dialect of ch'ti, also known as Picard. Despite the use of dialectal language, 600,000 copies of the DVD (which included French subtitles) were sold. No previous DVD featuring a one-man show had sold as well in France.^{[citation needed]}In February 2008, he released a film called Bienvenue chez les Ch'tis, a comedy based on prejudices held about the region, which went on to break French box-office records. Two weeks after its release the film had already been seen by five million people. After its fourth week this figure had risen to 15 million, and by 11 April, the film had surpassed the viewing audience of La Grande Vadrouille, having been watched by more than 17.4 million people.
