I'll be honest, I'm blagging my way through a stagewriting degree right now as someone who's seen 1000 films and read/watched about 30 plays, and that observation you just made has given me some much needed material to work with.
If you've got any anti-imperialist playwrights or even plays to recommend, I'd really appreciate it. I'm in the process of writing Operation Gideon by way of Dario Fo/Monty Python, and the writings coming along fine, but a chunk of the degree is justifying why I wrote what I wrote and who/what influenced it, which is what's giving me a headache. Can't art just be art for the sake of being, because it just feels right??? Ah well.
No worries if not. I don't mean to outsource my work.
