This is an interesting question. With Medical/law or other graduate schools, you should probably apply to as many as possible. However, film school is a little different. You want to try to get into the program that you feel is the right fit for you. If you don't get in, then I think it's much wiser to reapply the year after instead of trying to get into just any film school. But anyhow, without naming specifics, I would apply to at least three programs that you'd be interested in attending. Me personally, I applied to three, got rejected to all of them. Then the year after, I doubled the number and applied to six programs, and got accepted into four (two of which were schools I got rejected to the year before). In retrospect, reapplying to the same three would have been a wiser, less time consuming ordeal. Also, I get chills thinking this: What if my first year I applied to safety schools and got in then? Then I wouldn't be attending my dream school now... So yeah, don't apply to any place you consider a "safety." It's just not worth it, unless you know for sure you want to go there.
