How old were they supposed to be?
Although I don't think they could've found better actresses for Mona (Nathalie Press) and Tasmin (Emily Blunt); the choices sort of confused me as to their approximate ages. The fact that they were drinking and a smoking throughout the entire movie sort of confused me as well.
They both definitely appeared older than they were, and the characters seemed to act that way. But the the beauty of this film is that there are subtle hints as to the fact that they are still just high school girls/children, looking to appease their boredom. (Well, more so Tasmin whereas we see that Mona in a lot of ways, it still ignorant like a child.)
But, since Tasmin was of boarding school age and they were about the same age... what would you say? Sixteen, seventeen?
