Sorry for not using books in my examples. Since I am an aspiring screenwriter I watch a lot of movies when it comes to fiction. When writing an action sequence and how it effects the plot, there are different approaches you can take on which type of action sequence to use. Basically in my opinion, there are four types: 1. The Opportunity Action Sequence. This is the type of action sequence where something happens that gives either the hero or the villain, an opportunity to put a plan in motion. Sometimes the plan is premeditated before the action scene but it has to be successful in order to be considered this type of action scene. Such as in The Dark Knight for example, Bruce Wayne invades the building Lao is held in, in order to deliver him back to Gotham, thus kicking off the rest of the plot as a result of his plan. If however, the premeditated plan fails, which drives the rest of the plot, as a result of failing, it's called then this type of action scene in the next category: 2. The Dirty Rotten Luck Action Sequence This type of action scene has something misfortunate and often tragic, come out of it. Whether the hero or villain had a premeditated plan or not, the plan is ruined by something unforeseen, or something that he/she did not count on, happening. An example would be in Breaking Bad season 5, when Walt was hoping that the neo-nazi gang would rescue him from Jesse Pinkman, but his brother in law Hank shows up to his surprise, and the nazis end up murdering him instead. Having a villain escape capture, for example, is not enough to put it in this category. Not unless the villain escaping causes him/her to get more pissed off and come back at the hero hard, or vice versa. If the villain was going to come back at the hero anyway, whether or not this action sequence happened or not, then it falls under the No Consequence Action Sequence. 3. The Character Development Action Sequence This is pretty self explanatory as it creates a change in the character, causing him/her have an epiphany and take charge of the situation. The difference between this and the Opportunity Action Sequence, is nothing happens in this action sequence that creates an opportunity. It's a character change, rather than an opportunity opening up in the plot. An example of this would be in the original Mad Max. Even though his family is killed, it motivates him into action, but doesn't really effect the plot. 4. The No Consequence Action Sequence This is an action scene where the writers add one cause they think it will add suspenseful flavor but after it's over, everything is still the same, and no consequence has come forth, not in plot development, or in character change. And example, would be The Replacement Killers, where there were at least three action sequences, where the characters remained the same after nothing came out of it. Just to add flavor and that's it. These action scenes usually run in the opening as part of the hook, like Goldfinger, or they come and go in the first half of first two thirds mostly such as The Replacment Killers. But out of all these action sequence types, are they all good to use, and am I looking at them the right way? Is the 4th kind even worth choosing for a script just for flavor, even though there is no consequence?
