The shootout between Danny, Nicholas and the couple who were speaking to Reverend Shooter employs similar technical flourishes to Tony Scotts Man On Fire. Namely, when the two sides trade shots the action is often sped up or slowed down this is made possible by a hand-cranked camera, which Scott also used with aplomb. When Angel is shot by the aptly-named Reverend Shooter who uses slide-out pistols in a homage Martin Scorceses Taxi Driver Danny fears for the worst before running over to see his friend has been saved by the stab vest he spoke about earlier. This is a direct nod to the mithril coat from Lord of the Rings: The Fellowship of the Ring when Frodo is saved from being gored by a cave troll by his armour. In fact, the discovery that the armour has saved the respective character is played in the same in both movies. While its usually worn as an undergarment, it becomes visible on the chest and everyone looks at it in relief and wonderment. In this scene, the Reverend also calls Nicholas Grasshopper I wont say how, its a family list the nickname for Kwai Chang Caine in popular TV series Kung Fu.
