PRP Artefacts Ideas

So, one of my initial ideas for the first one is to re-edit a piece of existing film with different music to change it's atmosphere. I'm still not entirely sure whether to do this with just one scene from a film or attempt to make a re-edited trailer instead. Another idea I had is a short scene that I can edit in subtly different ways to make it either appear as a comedy, a horror, a drama, etc etc. but at the moment I'm having a few troubles trying to think of a basic, easily adaptable scene. It should be something fairly mundane to allow scope for the sound effect to drastically change our perception of what's happening on screen.
