Your question is a tad to vague. I'm assuming you're asking what other country other then where you are currently residing as that would just be a lazy answer.
England would top my list.
I guess some very cosmopolitan city in Canada might suit the bill as well. I would need a country which gets a sizable amount of theatrically releases, movie wise and a large art culture as well (museums and music concerts).
If speaking another language wasn't a problem for me, France would be high on my list as well.
