What move should I rent from iTunes, and how long do I have it for?

I am going to New York to see my Aunt and my cousins, and I wanted to
rent a movie on iTunes, but I can't think of a good one to rent. I
like comedy movies like The Benchwarmers, School of Rock, and Billy
Madison, but I have seen most of them. If worst comes to worst I will
rent one I have seen, but I would really like to see something new.
Thanks
