The Girl with Green Eyes, starring Rita Tushingham and Lynn Redgrave, is a 1964 film based on Edna O'Brien's novel The Lonely Girl about a brief affair between a working class shop girl up from the country and an older landowner.
It might not win too many prizes for its Irish accents, but it does retain some interest for its Dublin street scenes, and a great episode based around a night out dancing in a nightclub. Dancers are seen twisting on the floor to a live showband, and later in couples.
The scene is the Four Provinces Ballroom (or as it says on the sign 4 Provinces), which was apparently in Dublin's Harcourt Street and later became known as the Television Club before it was demolished in around 1990.
The nightclub scene kicks in around 6:30 into the film.
