For potential themes I'd add a lot of great TV shows, especially in recent years with the high level of funding and consequent 'golden age'. I know a lot of shows have been covered already, but the focus is still more on movies and music IMO, leaving a TV seam ready to be further mined.
Taking an off-piste example, a submarine theme based on Das Boot would be cool. That soundtrack... Obviously, Dekalog might be more challenging
I'd like more comedy themes too. Look at this list below- see what I mean?? Loads of potential themes.
