Hi senmut! I'm approaching it from the angle of being able to write for older books (e.g. Biggles), tv shows (e.g. Colditz) and films (e.g. To Be or Not To Be 1942). Write the fic I've always wanted to see sort of thing :D.

As well as more popular media.

I have also looked at my book/dvd shelves and jotting down fandoms to cover.
