Brainstorming: developing our idea's

After out previous brainstorming session, we have decided to delve into the sub genre of Religious Thrillers. In response to this idea, as a group we have decided to do the research into the following so that we can start to develop a better understanding of these genre's: 
The codes and conventions, the history of religious thrillers, a few analysis' analyse of the opening sequences of a couple of religious thrillers, plots that have been used in the past for religious thrillers.

We started brainstorming ideas and talked about religious thrillers that we had all watched, which in retrospective wast many so this is the reason we decided to go away and do some research on the topic. As a group we started to develop an idea for our film in where there would be a extremist catholic who captured and tortured people who had sinned, with his aim being to cleanse the population of people who he doesn't see deserve the gift of life. After a discussion and a brainstorm we all agreed that this could be a very good, different and interesting as religious thrillers are quite rare in the modern era of popular films.After deciding that we liked this plot idea, we brainstormed all of the ideas and anything that we thought we could include within the film in terms of plot, locations, props, narrative etc. Our ideas concluded to that the protagonist is living in a family home, perhaps with a family member in the scene at some point, then going downstairs or outside into a garage or a basement, where two people will be found to have been captured by him. We talked about how long each scene would take and what we would need for the planning and the making of the film. I think that this is a strong and different idea so far. The next stage of our development will be deciding on the finer details of the story and narrative and once this has been done we will start to storyboard.
