Make it possible to rank a film directly in the favorite list.Not som many clicks, just a "rank it" button.
Make it possible to edit the list directly, manually.
When doing rankings (especially earlier on) I also found that some movies where way down the list, when they are put in as comparison to another movie. Why not make it possible to mark them for later ranking? And when I feel for it I could just then press a rank the "marked for later ranking" button where all these films can be ranked by the 3-step comparison.

When it comes to errors/problem you could have a separate button where I can report if :

1. There is a duplicate of a movie in the list. I have seen a couple already, cloverfield for example.
2. Something is incorrect about the film. The year, spelling mistake etc..
3. If a trailer doesn't play (sometimes it just takes you to a black box) or if the audio is out of sync(which quite a big number of them are).
if you use buttons in the contexts of the problems, it is possible to automatically "catch" the movie name, trailer etc and the problem type (different buttons for different problems). In that way many more problems would be reported, since the users don't have to go through the process of manually writing a post and problems would get noticed earlier.

Make it clear when there is a movie that is done in two or more versions over the years, maybe with the whole picture ghosted, highlighted or something else that gets your attention. Otherwise there is a great risk of rating the wrong movie(which I have done for a couple already).
Or make a side note about it. Some films also share the same name. The film "Cypher" (2002) for example is also known as "Brainstorm", which also happens to be the name of a 1983 movie.

Some way of getting more information about the films that are ranked would be great, maybe like in IMDB where users write a summary about the plot, or is it even possible to link to that directly?
I have noticed that there often are some films that I have forgotten until I read the plot and remember that I saw the film. Or films where I can't remember all the details, but I can judge it more fairly if I read about the plot again. And (for international users) some films where the title was translated. This translation was more common before the mid 90;s(at least here i Sweden) and it seems like older films has less trailers, so that is also a potential problem.

Make it possible to rank films in the lower ranges, for example films that is at place 100-300. Or make it possible for the user to manually input the high and low range(any number).

Make it possible to suggest films that aren't in the database directly at the site with a form, maybe where the user is required to insert an imdb-link.

Make it possible to rank movies just by one director.
Make it possible to show different top lists. For example one based on the the users that has done the most rankings. Or by director or actor.

When it comes to the "hasn't seen" top list:
Make it possible to sort movies I haven't seen based on other things than just the top-chart list. By director, genre, year and so on, and in these "sublists" sort by where they are on the "overall" top-list.

Show the trend for a film, if it's moving up or down a certain list. If it's becoming more popular. Create a list based upon trends where the biggest mover upwards is the number one and so on. It's would possibly be a great way to put the highlight on lesser known films, which might be unfairly judged if nobody knows about them.
