No Surrender (1985) - Review
I remember seeing this movie in New York City when it was FIRST released. I was an adult at the time, as well. Sadly you can get an idea of how ancient am I.
I loved the movie despite a slight-anti Protestant bias, but I don't think we'll be seeing the same from the republican and loyalist leaders of the Troubles that started in 1969, unlike the previous generation of paramilitaries, due to the much higher degree of savagery and polarization.
