I officially took up my own full-time residence when I was 22 and in grad school. Had my own apartment for the first two years of grad school and then had roomies for my final year (yes, grad school took me three years instead of just two). then I moved back home for a year when I was 25 to save money for my wedding. Moved out a year later. My wife and I have been married for just over 2 years now.

Oh, and I would have liked Jude Law as Cruise's character. Michael Biehn wouldn't have been bad either. Both are pretty good at playing moody and disillusioned and both can be good with physically demanding roles as well.
