The fantasy epic Game of Thrones, filmed in Northern Ireland, has helped create around 800 jobs, Peter Robinson has said.
The First Minister told the Assembly it was a mistake to think such projects only provide work for actors.
Mr Robinson also said the movie Your Highness generated £12 million in direct spending in Northern Ireland from an investment of £1.15 million.
Game of Thrones, starring Conleth Hill, Ian McElhinney and Derek Halligan alongside lead actor Sean Bean, was shot mainly at Belfast's Paint Hall Studio in the Titanic Quarter.
"It's one of the largest studio spaces in Europe," Mr Robinson said.
"People very often look at the creative industries and they'll see a film or TV series being made and they'll think that's 20, 30, or 40 actors.
"In actual fact in this present project probably about 800 individuals have been employed at some stage of another.
"And it goes well beyond the actors."
He cited a series of professions ranging from technical staff to hairdressers and landscape gardeners who have been employed.
