I don't think he's living in Chinatown as he is still in high school in this film. Also, SPOILER ALERT, DO NOT READ IF YOU DO NOT WANT TO BE SPOILED.... I was on set yesterday and a production manager told us that they were filming a break up scene. Could be misleading, but I don't know.
May 14th may be trailer #4? I know a new one came out a week ago for The Avengers, but on the canadian website for trailer ratings, a new trailer called #4 was just rated.
This isn't necessarily good. They probably filmed everything with a PG-13 rating in mind. The only thing they can add in at this point to make it Rated R perhaps is CG blood. Whats the point?
