I'd move back to the UK. It's where I spent my childhood. I genuinely love Shakespeare, theatre and all that crap. Small studio in London, volunteer/work in the arts/cultural sector, go to the theatre or a tv recording during the weekend.
Unfortunately life is shit in the UK if you're not rich. I once calculated that I'd be better off staying unemployed where I live, than finding suitable employment in London. I have a couple of degrees, but starting wages were abysmal when you factored in cost of living (rent, etc.). A lot of money would also mean I can get another degree and get a visa. Also: private health insurance. The NHS ain't what it used to be.
Of course, if I was really rich I could also just stay where I am (low capital gain taxes), build a fully self-sufficient eco house (energy, water) then fly/drive/take the train to London, Berlin, Paris, Prague, Amsterdam for the weekend. Hell, buy a nice car, go for a drive.
