Studying Film, from CAS

<p>Hello! I'm going to be going to CAS next year (reeaally excited!), looking to major in Economics/Mathematics. But, I really want to study film as well. </p>

<p>I read about the Cinema Studies major at Tisch, which is open to CAS students (more or less). Is it easy to do?</p>

<p>If I really got serious about it, and wanted to concentrate solely on film, how difficult would it be to transfer to Tisch? I'm guessing I need a portfolio?</p>
