That’s the end of the line. The hero / heroine is finally in the villain’s clutches. The victory seems imminent. And it is at that moment that the villain can no longer keep his thoughts to himself. In a long monologue, the villain takes time to spell the entire evil plan.
It’s the monologue moment, quite often, that turns out to be the villain’s regret. Like in “The Good, the Bad, and the Ugly,” where a vengeful attacker corners Tuco (the “ugly”) and begins to rave about having spent weeks tracking him down. This gives Tuco enough time to shoot the attacker and remark, “When to shoot …. shoot, do not speak! “Recently in” Godzilla vs. King “was the evil CEO Walter Simmons (Demián Bichir) too busy blabbering on about his plans to notice Mechagodzilla sneaking behind him to swallow him. You know you monologue way too hard when you don’t even notice a giant mechanical monstrosity right behind you.
In general, it would be a good idea for a film villain to just quietly work until they actually achieve success in their plans, and to save the monologue for their autobiography. Sure, it can be tiring to come up with a clever plan and not be able to tell anyone. But just remember that evil planning is a marathon, not a sprint, and you should not try to rush over the finish line.
