Problem: Once is a 2007 Irish romantic musical drama film written and directed by John Carney. The film stars Glen Hansard and Marketa Irglova as two struggling musicians in Dublin, Ireland. Hansard and Irglova had previously performed music as the Swell Season, and composed and performed the film's original songs. Once spent years in development with the Irish Film Board and was made for a budget of EUR112,000.

A rough cut of the film was previewed on 15 July 2006 at the Galway Film Fleadh, but the film was subsequently turned down by several prestigious European film festivals. However, once finished, it secured spots at the 2007 Sundance Film Festival on 20 January 2007 and the Dublin Film Festival in February 2007, and received the audience awards at both events.  The film was first released on cinema in Ireland on 23 March 2007, followed by a limited release in the United States on 16 May 2007. After its second weekend in release in the United States and Canada, the film topped the 23 May 2007 indieWIRE box office chart with nearly $31,000 average per location. As of 28 March 2009, Once has grossed nearly $9.5 million in North America and over $20 million worldwide. After 2007's box office success and critical acclaim, it won the Independent Spirit Award for Best Foreign Film. Steven Spielberg was quoted as saying "A little movie called Once gave me enough inspiration to last the rest of the year". When informed of Spielberg's comments, director John Carney told Sky News, "in the end of the day, he's just a guy with a beard". At the time of this interview, Carney himself was also wearing a beard.  The song "Falling Slowly" won the 2007 Academy Award for Best Original Song. The nomination's eligibility for the Oscar was initially questioned, as versions of the song had been released on The Cost and The Swell Season albums, but this was resolved before the voting for the award took place. The AMPAS music committee satisfied themselves that the song had indeed been written for the film and determined that, in the course of the film's protracted production, the composers had "played the song in some venues that were deemed inconsequential enough to not change the song's eligibility".

What is the song?

Answer with quotes: The song "Falling Slowly"


Problem: Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.

For most of the Gaelic period, dwellings and farm buildings were circular with conical thatched roofs (see roundhouse). Square and rectangle-shaped buildings gradually became more common, and by the 14th or 15th century they had replaced round buildings completely. In some areas, buildings were made mostly of stone. In others, they were built of timber, wattle and daub, or a mix of materials. Most ancient and early medieval stone buildings were of dry stone construction. Some buildings would have had glass windows. Among the wealthy, it was common for women to have their own 'apartment' called a grianan (anglicized "greenan") in the sunniest part of the homestead.  The dwellings of freemen and their families were often surrounded by a circular rampart called a "ringfort". There are two main kinds of ringfort. The rath is an earthen ringfort, averaging 30m diameter, with a dry outside ditch. The cathair or caiseal is a stone ringfort. The ringfort would typically have enclosed the family home, small farm buildings or workshops, and animal pens. Most date to the period 500-1000 CE and there is evidence of large-scale ringfort desertion at the end of the first millennium. The remains of between 30,000 and 40,000 lasted into the 19th century to be mapped by Ordnance Survey Ireland. Another kind of native dwelling was the crannog, which were roundhouses built on artificial islands in lakes.  There were very few nucleated settlements in Gaelic areas. However, after the 5th century some monasteries became the heart of small "monastic towns". By the 10th century the Norse-Gaelic ports of Dublin, Wexford, Cork and Limerick had grown into substantial settlements. It was at this time, perhaps as a response to Viking raids, that many of the Irish round towers were built.  In the fifty years before the Norman invasion, the term "castle" (Old Irish: caistel/caislen) appears in Gaelic writings, although there are no surviving examples of pre-Norman castles. After the invasion, the Normans built motte-and-bailey castles in the areas they occupied, some of which were converted from ringforts. By 1300 "some mottes, especially in frontier areas, had almost certainly been built by the Gaelic Irish in imitation". The Normans gradually replaced wooden motte-and-baileys with stone castles and tower houses. Tower houses are free-standing multi-storey stone towers usually surrounded by a wall (see bawn) and ancillary buildings. Gaelic families had begun to build their own tower houses by the 15th century. As many as 7000 may have been built, but they were rare in areas with little Norman settlement or contact. They are concentrated in counties Limerick and Clare but are lacking in Ulster, except the area around Strangford Lough.  In Gaelic law, a 'sanctuary' called a maighin digona surrounded each person's dwelling. The maighin digona's size varied according to the owner's rank. In the case of a boaire it stretched as far as he, while sitting at his house, could cast a cnairsech (variously described as a spear or sledgehammer). The owner of a maighin digona could offer its protection to someone fleeing from pursuers, who would then have to bring that person to justice by lawful means.
