In 1975-based British / Irish drama "Dead Shot" (aka "Borderland") when his pregnant wife is killed by British soldier Ami Ameen, IRA paramilitary Colin Morgan (under handlers Felicity Jones & Tom Vaughan-Lawlor) heads to London seeking revenge... by which time Ameen is in Mark Strong's unofficial unit hunting down the very bomb-planting / murdering terrorist cell Morgan's now in. Second-time co-directors Charles & Tom Guard nail the period details & tone superbly, and their debut as co-writers is also impressive (though does lose some of its early energy prior to its effective ending). It's a a good film and a fine entry to a dark, bleak, gritty, high-quality genre.
