Reminds me of Hostel somehow. I couldn't resist watching the film (not sure if I watched the sequel). It made me feel really sick. Somehow nothing shocked me when I was little, but now it does!
To become a British citizen, I would have to apply for naturalisation and take the Life in the UK test, which is multiple choice and based on a particular handbook. That's all, really, except you have to then go to the ceremony and swear an oath to make it official.
Today I am also listening to the Moulin Rouge soundtrack.
