DISQUS is a distributed comments system. Django integration is available as a module: http://github.com/arthurk/django-disqus/tree/master
We could add disqus as an alternative commenting system.

This would have to work EXCEPT the current system, not instead of it.
E.g.
- if a user is signed into Filmaster, do not show the DISQUS commenting form, only the disqus comments
- if a user is not signed in, offer them to sign in using DISQUS to comment
- if the user is signed in using DISQUS, show the DISQUS comment form and allo the users to comment via DISQUS

Problems:
- How can we make the DISQUS users Filmaster users so that they could also rate movies, post blog posts and reviews, etc? More like a DISQUS as an OpenID alternative?
- How to display the two threads of comments: the native one and the DISQUS one?
