Honestly, it depends on the level of interest.
The problem is we have very few high quality, consistent contributors and unless people really wanted a Movies section and plenty of contributors were willing to jump on it, it's a hard sell.
Artists / Bands typically release several albums, they have many concerts and can be active for years, TV shows typically have several seasons, again remaining active for years, movies on the other hand are typically a one shot deal.
The amount of work that would be required to fill out a Movie section would be tremendous, I'll be honest, I would love to have a Movies section, it would nicely round out the site, but, without commitment from a lot of contributors, I can't see it happening.
Moderating the site is hard work, and moderators have historically not hung around much after their own collection was finished, the problem with this is, if you take away the contributors who consistently provide high quality images (leepenny for example), the people who submit really crappy images far exceeds those who provide acceptable ones.
This means moderators have to spend a long time going through the images, weeding out the bad ones, denying them and telling the user why they are denied (and where possible with some tips on what to do), with a section like movies where it's a one shot deal, it's very likely the amount of crappy images being submitted could explode.
So basically if a few people want to step up and moderate a movie section, and a fair few contributors (who have a history or quality submissions) were commited, I'd be more than happy to add the section.
Hope that helps
