Many of the documents relate to the 1996 production of "Michael Collins", which starred Liam Neeson as the Irish patriot and revolutionary.

The collection includes a poster seeking to recruit 5,000 male extras for the filming of a recreation of Bloody Sunday. It says only men are sought, but women are welcome if they are dressed in men’s clothes. It reads that those wishing to be cast should only wear dark pants and coats and not jeans, runners, or watches.

National Library Director Sandra Collins it was important that the collection remained in Ireland, as various institutions in the U.S. were interested in obtaining the archive.

She said it will take the library’s archivists about a year to sort through the documents and digitize them.
