I discovered this short Irish movie thanks to Novroz. I hadn’t heard of it. It is well done but admittedly very short. There doesn’t seem to be any intention of making a full length movie out of The Silent City. I have a feeling they quote quite a few movies. Starship Troopers and Behind Enemy Lines?  The back of the uniforms look like backbones. I was also reminded of District 9. Definitely a Sci-Fi thing ging on here. Be it as it may, watch it, it’s worth it.
