Obviously, good action movies also contain (possibly faked or real) arm amputees,
Fiction movie Iron Man 3 (imbd | wikipedia), directed by Shane Black (wikipedia), with movie script written at least in part by Drew Pearce (wikipedia). The last movie with a similarly weird focus that I posted about was Hancock (2008).
The "good" guy - Iron Man by Tony Stark - works with a lot of highly sophisticated prosthetic add-ons in order to be invulnerable. Through a shell, or armor, or body casing, featuring lots of gimmicks, Tony Stark turns himself into "Iron Man", a soldier that can fly and fight really hard, and that is practically invulnerable (as long as his batteries do not run out).
The "evil" guys in this movie try to be invulnerable by altering their own bodies in a more biological way - so after injecting some stuff dubbed "Extremis Virus", they not only "heal" fast, they also grow back skin, limbs, anything. They become weapon-grade soldiers without extra batteries or extra weight to schlepp around. The problem that they have is that, eventually, the one or other "evil" guy overheats and explodes.
Now as we all know, of course, missing limbs can be either fitted with mechanical or even battery driven prosthetic limbs. Or they can be re-grown, transplanted, to achieve a more "biological" solution to fixing the absence of the missing limb.
Interestingly, two amputees are portrayed on the "evil" side. There are no amputees to be seen on the "good" side.
One is a woman that appears to be an arm amputee as consequence of some injury. She later gets herself injected with the "evil" stuff which grows back her limb (but does not heal her facial scar, funnily enough). The other is a girl that appears to congenitally miss part of her right leg, but she is also the daughter of the vice president of the USA, who himself supports the evil project - obviously to get them to "heal" his daughter from being an amputee.
What are they doing there?
