Replace John Williams’ score with Charles Trenet’s “Boum!” during the Order 66 montage.
This idea is so good it has been nagging at me so I slapped this together only using Boum for audio (apologies for video quality issues). I made some fast and dirty edits to get the first boum and scene changes lined up a little better, but it was halfway there on its own. The two best moments lined up without any alteration and the camera work goes so well - watch to the end. There is some natural synchronicity between the lyrics and what is on screen. This could really be finessed into something brilliant I think.
