Kills from animated characters (where the actor only does the voice-over) DO NOT count.
Motion capture performances count but the kills are given to the actor doing the mo-cap for the body not the face if both are done by a different performer.
For films with multiple cuts/versions, the cut/version with the highest number of kills for the actor is represented.
Information regarding kills present only in other versions are counted as canon and is taking into consideration if the new version doesn’t counter it with a different set of circumstances.
For a kill to be counted the victim has to be seen dead after or alive at some point in the film. Photographs and the like count.
A single body part can count too if this is confirmed in the film to be proof of the kill.
Deaths of unconscious/bound people from fires, explosions, etc. go to the actor who caused the fire, explosion, etc., not the person who knocked out or bound the victim.
Manned vehicles (where actual bodies are not shown) are counted with the absolute minimum number of people needed to keep the vehicle manned (e.g. A destroyed moving car with no bodies is one kill and a destroyed, manned train with no bodies is two kills).
Robots count if played by an actor, otherwise only sentient, organic beings count.
Kills go to the credited actor, not the behind-the-scenes stuntman/stand-in performing the “kill.”
When a character is played by multiple credited actors (not including stuntmen/stand-ins), the kill only goes to the actor playing the character at the time.
Kills can be shared by actors if more than one deliver a killing blow at the same time.
If a group of characters are all shooting at others and the kills can’t be clearly attributed to any one character the kills are shared equally with one kill giving to both in case of an odd number.
Kills in in-universe movies/TV shows count if we see the kill framed in the way an audience would see in the finished film/show, so a behind the scenes look at a performance doesn’t count.
Imagined kills that don’t actually take place in-universe count if they meet the rest of the criteria.
Accidental suicides, deliberate self-kills, and fatal “heroic sacrifices” count.
