* Carefully trash their personalities. Study their mannerisms and exaggerate them to make them clownish and stupid (and yet, achieve a level of accuracy in many details). Make them laugh like they are retarded, and exaggerate their accent: this is vital. [See the scenes in Oliver Stone’s “Nixon” in which the colors are inverted whenever the main character laughs.] Heavily outline and relentlessly repeat a few of the character’s mannerisms so violently that you cannot watch the actual person anymore without cringing.
* Present the content of their “personalities” as: cold and depressing (yet with a violent temper), spoiled in reactions and judgement, selfish in conduct, and always biting the hand that feeds them at every single turn. Include scenes in which they are incapable of doing basic household tasks such as their own laundry, or using the toilet, and furthermore react viciously to the help of others. (Begin the film with the subject as a spoilt brat child: this gets the audience to hate him immediately, and is always eminently plausible. Viewing him as a character in a narrative one simply hates him without any limits or qualifications.)
* Present the content of their “personalities” with as many low-class elements as possible: that is, depict them as foul-mouthed toilet talkers in private.
* Most important: accuse them of heinous yet plausible acts, digging dirt as much as possible that would permanently black out any “repyutashun” they might have. If they are ever accused of any sexual misdemeanor, even by a tabloid, simply cut open this wound and rub as much salt on it as possible. Depict them having illicit sex with married women/men, and include detailed sound effects. Create individual stand-alone scenes that are semi-plausible but have no direct source anywhere; e.g. throw in a line or two suggesting that they are pedophiles, incestuous, alcoholic, or are abusive parents (monsters, in other words). Then move on. Even if the main narrative is challenged, the details would continue to do their damage. (At worst, it would still seem from the outside that there is a legitimate “controversy” over the film.)
* Make the character extremely plausible and “complex”, so that an innocent viewer won’t have any suspicion of any intent to destroy someone: in fact, he will have something of the *opposite* impression, that they are made to look better than they really are.
