13 or a very convincing person
no
In north America, you can see it at any age, but if you're under 13 years old you have to be accompanied by an adult.
In all 50 states, you have to be 17 to see an R rated movie, unless an adult buys your ticket and sees the film with you.
18 unless accompanied by an adult over 18.
Yes, they can. But I'd advise you not, and you wait.
No
Yes. A 13-year-old can go see Paranormal Activity 2 (or any R-rated movie) if accompanied by an adult.
Typically, one must be at least 17 years old to see an R-rated movie. However, age restrictions can vary by country and theater policies. Some theaters may allow minors to enter R-rated movies if accompanied by an adult.
PG stands for Parental Guidance suggested. You can be of any age to see one, especially with an adult, since if you are under the age of 13 or so you would be less likely to go see a movie on your own- so any age can see the movie. To see a PG-13 movie on your own you have to be 13; R rated is 17.
There are no age restrictions for G, PG or PG-13 movies. The only age restrictions are for R and NC-17 movies. Persons under 17 need an adult chaperone to see an R movie. Persons under 17 cannot see an NC-17 movie in theatres at all, not even with an adult.
I don't really think there is an age limit. But for example, if the movie is not appropriate for you, you should be with an adult. However, if your age is too young (for example: if you want to see the movie Harry Potter and the Deathly Hallows part 2, but you are five to eight years old) i recommend avoiding the movie.
If you wish to see a movie that requires minors to be accompanied by an adult, then any adult qualifies. But it may not be a good idea to ask random strangers on the street to take you to a movie.
