A strange list for a pacifist, tree huggin', war protestin' guy like me to write, but guns in movies are sometimes very cool and anything cool can and should be put in a top 10 list.
A gun so iconic it has a whole James Bond movie named after it, this weapon was a one-hit-one-kill weapon with ammunition designed for maximum damage to the target once hit. Designed to illustrate Scaramanga’s (played by the ultimate bad guy Chistopher Lee’s) peerless marksmanship, The Golden Gun has gone on to become a classic videogame weapon and gametype, where the players all attempt to get the lethal weapon first.
Not a great movie, but a great scene, especially if you’ve got some kind of problem with Jack Black (come on, he’s hillarious!). This weapon has the added bonus that you don’t need to be there to use it, and accuracy shouldn’t be too much of a problem.
A weapon made awesome not by its destructive power or it look, but by how its reloaded. James Cameron knew how to make an action scene back when he made T2, and Arnie taking on the T1000′s truck with this gun was a great example.
Based on the Barrett M82A1 sniper rifle, but firing grenade rounds, the Cobra Assault Cannon is provided by Dick Jones (greatest movie bad guy ever) to Clarence Bodicker and his cronies to take out Robocop. This doesn’t exaclty go to plan as one of the henchmen is blown to pieces with a Cobra by Lewis and even the mighty ED-209 is felled with one by Robocop himself.
