Thriller titles

During the opening scenes, I've seen a number of thrillers that have an introductory scene, then begin the title credits. I think this is quite an interesting idea, as it sets the atmosphere before we know the feeling of the film (the font of the opening titles plays a huge impact on what sort of film this will be, for example most Disney films are usually very bright, bold & colourful, so the viewers know this will be a film with a happy ending.) In thrillers, there doesn't have to be a happy ending, the film can just end. Usually there is a significant point at which the film ends, usually when someone saves the day or someone has been put to justice. Early ideas for our thriller was a terrorist attack, but starting at the end. So the first thing people will see is destroyed buildings, people's dead bodies, fire, destruction, etc. Then throughout the opening scenes, we'll have flashbacks to earlier events to the build up. This might be tricky as the thriller opening is only meant to be a few minutes long, and with the titles, it might be hard to convey everything we want and still have the viewers understand what is going on. An idea that was built on the terrorist idea was that until the first flashback, it was complete silence except for maybe a sad, slow song - as the actor/actress looks around at the chaos. This is not for certain yet though.
