Err, probably....not, because:
a) Harry Potter appeals to a greater demographic audience, i.e. young children all the way up to the older generations enjoy the books/movies,
b)the Harry Potter فلمیں have already shown HUGE global success, just have a look at ticket sales for yourselves...

[c)Parents with younger children will most likely take them to see Harry Potter, than New Moon, at the cinema a s it comes across as a مزید family friendly/related film.]
But, I might be oh so slightly(i.e.VERY) biased...=D
