Playboy of the western World (1962) – A milestone in the cannon of English language theatre in Ireland. | Ryan’s Daughter (1970) - This multi award winning film based upon Flaubert’s Madame Bovary is renowned for its depiction of Ireland’s glorious scenery captured on film by Freddie Young. |

This led me to Atlantic Film Trail.

As a tourist route map, it could form as good a basis as many other suggestions…..
