You can do it programmatically, but it's a kind of hack. If you enable the Facebook Comments plugin, it will automatically create a page for you. Therefore, if you create a shared web page that accepts parameters such as movieID, you can make a script that executes an HTTP GET for each identifier you have, and all graph objects will be created.
Like this:
<fb:comments href="www.mypage.com?id=<%=request.getParameter("movieid")%>" num_posts="35" width="340" colorscheme="light"></fb:comments>
