Welcome to the Q&A Forum

Not from the duplicate content per se, but I assume the websites are low quality and wouldnt give you benefit in the first place.

It is duplicate content. However, that might be the least of your concerns.  You are going to have to compete directly with Vimeo, Youtube, IMDB and the companies that produce these movies.  That's a lot of high dollar companies to fight with for rankings.

super SPAM! Protein, real estate, cell phones? They have nothing in common. Please read the beginners guide to SEO. This will help you with these sorts of questions: http://www.seomoz.org/beginners-guide-to-seo

Try to avoid generating (or worse, buying) +1 votes from untrustworthy sources. My advice to you is this: build a great Google+ page for your website (fill all the details, and even add content, as valuable as you can). Then, check the top 50 pages on Google+. Add them to your circles. And wait. People will start appearing from the network and will start adding you on their circles. When you get the first 100, use the share options of the circle and write something like this: "If you like our content/info, please give us your vote by clicking on the +1 button on our front page" and place a link to your entrance page. Now you'll get natural and good votes. And, yes, in my opinion, because of the trends on the market, with social media becoming a key factor, I even suspect that soon the +1 will indeed replace the PR (Page Rank).

What is Sandbox? In order to avoid something like Sandbox, one should know very well what Sandbox is. But, nobody knows if Sandbox does exist, so let's just focus on the main problem here: How do I get my pages indexed? I have tried over years a lot of techniques, but I found only one that seems to work. If your site is not dynamic, make it so. Create the sitemap and the feed (I recommend RSS 2.0). Put your sitemap in your robots.txt. (last line, like this: Sitemap: http://www.yourdomainname.com/sitemap.xml). Submit sitemap to Sitemaps section in your Webmaster Tools' account. Submit your RSS feed to main RSS directories (just google the words, and you'll find plenty of them). Start with FeedBurner, to please Google. Wait a week or so and you'll see that your pages will start appearing in index. Good luck!

Right. And some of the backlinks you earn from the initial no-follow links can be very valuable. Reporters often begin research with Wikipedia.

A quick couple of things you may want to focus on: : Instead of just using the movie title, incorporate creative uses of keywords you would like to rank for.  Start by doing a little bit of keyword research and see what looks competitive and what doesn't.  Not a huge impact but will help. Category Pages: From what I can tell all of your category pages "/category/crime" do not contain any tags.  I would see if you can find a way to have an for these pages. Alt Tags: I would vary what you use for your alt tags.  Instead of just using "Movies 2012". I see you have the XML sitemap and you may want to consider just creating a basic HTML Sitemap for the footer. Also because this works well for movies but can require a little effort, I will just throw it out there as something to look at: http://schema.org/

Yes I agree. Content is still King (ish).
