I am currently working on a script/play that uses this convention known as breaking the fourth wall i.e. the imaginary wall that separates the audience from the work of fiction. While i'm enjoying trying this new style out i find it difficult to keep the "wall" from being broken too frequently otherwise it just doesn't work. I've looked around for many examples of this and found that movies like Kiss Kiss Bang Bang was pretty good with this and even Fight Club, even if it was just for a second. The most exciting example i came across was a short play written by Stephen fry in which the main character is a teacher and his students are literally the crowd. He ushers in the late comers and scolds slouches, very entertaining. I was wondering if anyone else has tried this and how their experiences with it went or has any other examples of this.
