As suggested by one of our comments (Thanks, Benjamin!) here is another resource for making your bibliographies online. It's http://www.bibme.org/.
You can search within different media, including film. Once your source comes up, you simply select it, add in a few specifics and it's added to your bibliography. You can even select from different formats: MLA, APA, and Chicago. It looks very easy to use.
If you have ever used it, let us know what you think or share some other web resources that you use for your projects.
