Question: What film about the trafficking of children did an actor from Northern IReland who starred in Excalibur and The Bouny star in?

<P0-S0> Elephant is a 1989 British short film directed by Alan Clarke and produced by Danny Boyle. <P0-S1>  The film is set in Northern Ireland during the Troubles and its title comes from Bernard MacLaverty's description of the conflict as "the elephant in our living room" — a reference to the collective denial of the underlying social problems of Northern Ireland. <P0-S2>  Produced by BBC Northern Ireland, it first screened on BBC2 in 1989. <P0-S3>  The film was first conceived by Boyle, who was working as a producer for BBC Northern Ireland at the time. <SEP> <P1-S0> The Ulster Banner (Ulster-Scots: "Ulstèr Bannèr"; Irish: "Meirge Uladh" ) is a heraldic banner taken from the former coat of arms of Northern Ireland, consisting of a red cross on a white field, upon which is a crowned six-pointed star with a red hand in the centre. <P1-S1>  It was the flag of the former Government of Northern Ireland and common flag of Northern Ireland from 1953 until that government was abolished in 1972. <P1-S2>  It was adopted to mark the coronation of Queen Elizabeth II, and was first flown over Parliament Buildings on 1 July 1953, in honour of the Queen's visit. <P1-S3>  The Minister of Home Affairs announced that, while the Union Jack was the only standard officially recognised, those who wished to have a distinctive Ulster symbol might use the banner. <P1-S4>  Since 1972, the Ulster Banner has had no official status and is not used by the current Northern Ireland government or by the British government. <P1-S5>  However, the Ulster Banner is still in common use by loyalists/unionists, and to represent Northern Ireland internationally in some sporting competitions. <P1-S6>  It has become a symbol of Ulster loyalism and is a contentious symbol. <P1-S7>  In recent years there have been calls for a new, neutral flag for Northern Ireland to replace the Ulster Banner. <SEP> <P2-S0>  In 1976, he joined the Lyric Players' Theatre in Belfast for two years. <P2-S1>  He then acted in the Arthurian film, "Excalibur" (1981). <P2-S2> Liam John Neeson OBE (born 7 June 1952) is an actor from Northern Ireland. <P2-S3>  Between 1982 and 1987, Neeson starred in five films, most notably alongside Mel Gibson and Anthony Hopkins in "The Bounty" (1984), and Robert De Niro and Jeremy Irons in "The Mission" (1986). <P2-S4>  He landed a leading role alongside Patrick Swayze in "Next of Kin" (1989). <SEP> <P3-S0> Susan Bissell is the Director of the Global Partnership to End Violence Against Children. <P3-S1>  After acting in "Taken", a film about the trafficking of children, Liam Neeson was inspired to combat child abuse, and, in July 2013, Bissell voiced her belief that Neeson's work on this issue would be effective. <P3-S2>  She was previously UNICEF's Child Protection Section chief. <P3-S3>  She is a Doctor of Philosophy. <P3-S4>  She does not oppose international adoption, but believes that it is preferable for abandoned children to be taken back by their previous families and advises governments to provide small monetary incentives to families who are willing to do so. <P3-S5>  She opposes the concept that there is a global orphan crisis, and believes that "the crisis is something else... a child protection crisis." <P3-S6>  In 2000, her research on child labour in Bangladesh was published. <P3-S7>  In 2007, she spoke at the Atlantic Canada Child Welfare Forum in Halifax Regional Municipality, Nova Scotia, Canada, saying that the country should prohibit all forms of corporal punishment in the home, including spanking. <P3-S8>  In 2009, she spoke in Dar es Salaam, Tanzania, saying that steps needed to be taken in the country to address the causes of child labour. <P3-S9>  She identified the abolishment of primary school tuition payments as a good way to address these causes. <P3-S10>  In 2011, when UNICEF was criticized for not acting on non-governmental organizations' claims that there was systematic use of child labour in Uzbekistan, Bissell said, "We're not police. <P3-S11>  We're not monitors."
