Does anyone know if you have to be EXACTLY 17 to...?

So i heard Bruno was a really funny movie and i wanna see it. But the movie theaters are being really strict on that particular movie and checking ID's and tickets once step inside.. Im 16 and turning 17 in 2 weeks do you think theyll let me in? i have a drivers license ID and everything. And usually what i do is buy a ticket for a different movie thats playing at the same time and just go in that one, but i really dont want to risk it this time? So does anyone know if you have to be EXACTLY 17?
