You can find movie references in the weirdest places: I found this one in a 30+ year old book that I've read (Szasz Janos: Amerikabol Jottem).

This is nice: how to get your code into the address space of an other process? Just pass it at the command line (then locate it in the new process and CreateRemoteThread :-). An other variation of this might be to pass it in the environment block (although the program might act weirder than with a funky command line…). For both methods you need a shellcode which doesn't contain zeroes!
