I think "recommendation" will be a killer feature of the site, even if it doesn't approach the philosophy behind letterboxd (being a social site).
Moreover now that you are at the beta stage, meaning fewer users, less probability of "friends", the recommendation of a movie based on my most liked movies or the highest rating, it'll be a great way of discovering new movies.
I know that technically it will very challenging or maybe you have even think about it.

Add a match button to every profile so you can check immediately if somebody has the same taste as you.

You can use the like and/or rating of a movie to produce a list of similar movies/similar profile or a similar %.

I'd like the option if keeping my account private, like how Twitter handles private accounts.

I imagine some kind of inbox or notification system where you can receive suggests from your friends. The film menu you see on mouse over can get an extra option "Suggest to friend..."

The title says it all, yo. I've personally seen at least three people asking for a similar feature. Adding a button that would randomly choose a movie in your watchlist for you.

What you could do if you were feeling all kinds of fancy is even adding the ability of letting the user input a tag, to help you choose a movie in its watchlist.

Enable users to create groups they can join, such as "Filmspotting fans," "365 Movies in 365 Days" or groups by location, etc. sort of like Facebook groups.

Since there is an App on Itunes, I think it would be a great idea to make one for Android. Not everyone has an Iphone, I simply prefer Androids. I love the interface which you displayed on the preview on the website, I hope this goes through soon!

Besides liking a list, I think it would be nice if you can follow a list. Some lists will change or grow over time and it would be nice if people get a notification in their activity of it when they choose to follow a list.

Allow a list being 'open' which then users can follow a list and add films to it. This will result in much more list activity and complete film lists.

Take for example http://letterboxd.com/pablos/list/special-powers/. I can easily add 10 more movies without any effort to make the list more complete.

Optional: to demotivate abuse, submitted films must be allowed by the list owner before being added.

Please let me be able to fully remove users like Todd Gains, Cogerson and Naughty who just ruin the website for me. Their reviews are dreadful and I find I can't visit the homepage because their awful rubbish is plastered everywhere.

I'd love for letterboxd to have an xbmc plugin (www.xbmc.org) which would allow to import your movie collection as well as collect seen/unseen data automatically. The option to rate a movie aftter watching it could be added too! Take a look at www.trakt.tv they have such a plugin and i think it would be awesome if letterboxd had something similar! Thanks
PS I`m typing this from my couch, in font of my win7/xbmc htpc powered home theater ;)

I often find that I want to list things other than films. It would be great if I could create a list of, for example, the Best Directors. Or list my Favourite Japanese Actresses. Or make a list of popular Animation Studios.

Please add the watchlist to the data export.

Thank you!

My current watchlist is 500 films deep. Trying to find something to watch strictly from flipping through the cover view is a bit tedious.

If we could categorize films within the watchlist (I might do my own by genre) it might offer some relief. Then, when the film is watched, it would still disappear from your watchlist instead of having to be manually removed from a list you've created.

For example, you could have
1. Citizen Kane
2. The Godfather
2. The Godfather Part II
3. Blade Runner

This shows that the two are considered to be equal on the list and doesn't mess up the numbering for the rest of the list.

Pull our movie viewing history from Trakt into Letterboxd. Maybe also sync our ratings and/or reviews between the services...

When you watch a movie in Plex it marks it as watched here and at the end, it gives you an option to review/rate it which shows up here and that you can toggle on or off.

Just a thought, but not sure whether it's possible or not. Seems likely and it'd certainly urge me to permanently use the service.

Stunning work so far! Keep it up.

Most reviews are and will be written in English. But once public accessible this site will (hopefully) grow, so will the number of reviews and diversity of languages used to write these reviews. On a movie detail I can see 3 popular reviews in 3 different languages for example.

Maybe an options where you can select in what language your review is written and an option (checkboxes) to select which languages you understand... and wan't to see.
