Every 10 years since 1952, the British Film Institute's Sight & Sound Magazine has asked film scholars, critics and directors to submit a list of their top 10 movies of all time. Those lists are combined and scores are tallied up and, each decade, in the year ending in "-2," a new list of the 10 greatest films is released.

As Roger Ebert (a Sight & Sound voter) once wrote of the Sight & Sound List: "It is by far the most respected of the countless polls of great movies--the only one most serious movie people take seriously."

2012's Sight & Sound list came out Wednesday, and if you're like us, you immediately scrolled through it to check off which films you had seen and which you hadn't. And while most of you have probably seen "Citizen Kane (you havent?!?!), a few of the more obscure, experimental or Russian films may have slipped under your radar.

No more! We've compiled the streaming video websites where you can legally -- and, occasionally, for free -- watch each of the ten Sight & Sound films online.

A note on methodology: First, we searched for free options -- many public domain films are available gratis online; then, we trawled the subscription websites like Netflix, Hulu Plus and Amazon Prime; finally, if neither of those brought any results, we searched Amazon Instant, iTunes, and Vudu to see which service offered the film for online rental for the cheapest. We're not going to link to any torrent sites or suspect YouTube uploads, though many classics can, indeed, be found through a simple search of the film title through YouTube.

Here's what we found. No more excuses for not having seen the 1929 experimental film "Man With A Movie Camera" (since we know you're making excuses about that constantly): Hook up your laptop to the big screen and get watching.

1. "Vertigo" (Alfred Hitchcock, 1958) - Sight & Sound voters left their hearts in San Francisco this time around. Find out why by renting Hitchcock's dark, mysterious masterpiece from Amazon for $2.99 or $3.99 on iTunes. We also found it for free on YouTube.

2. "Citizen Kane" (Orson Welles, 1941) - Did you know that the source of the Internet's most ageless GIFs is also a pretty good movie in its own right? YouTube has it for $1.99, Vudu and Amazon have it for $2.99, and an iTunes rental is $3.99.

3. "Tokyo Story" (Yasujiro Ozu, 1953) - Contrary to popular belief, Ozu's tale of parental abandonment and existential grief in postwar Japan is not the inspiration for Pixar's "Toy Story"; it is, however, the third greatest film of all time, according to Sight & Sound. Hulu Plus subscribers can watch for free (thanks to an ongoing partnership that makes Criterion Collection films part of the catalogue); the rest of us will have to pony up $2.99 on Amazon or $3.99 on iTunes.

4. "The Rules of the Game" (Jean Renoir, 1939) - Watch rich French people try to seduce each other in this classic, available for free for Hulu Plus members and for $2.99 on Amazon.

5. "Sunrise: a Song for Two Humans" (F.W. Murnau, 1927) - Movies of a certain age fall in to the public domain, meaning the copyright lapses and anyone can use it. Murnau's "Sunrise" is the first such film on the Sight & Sound list to do so. You can stream it on the Internet Archive site here.

6. "2001: A Space Odyssey" (Stanley Kubrick, 1968) - I'm afraid you can't stream this anymore, Dave: Kubrick's films just disappeared from Netflix's streaming section, so you're gonna have to pay for a rental (unless you search YouTube). YouTube also has the cheapest rental of the sci-fi classic: It's just $1.99 to rent 2001: A Space Odyssey, which is not only a stunning, groundbreaking film, but also contains the origin of Apple's iPad (kidding!).

7. "The Searchers" (John Ford, 1956) - Got Amazon Prime? You can watch The Searchers for free! John Wayne is the good guy (maybe!) in what many consider to be the greatest Western of all time.

8. "Man with a Movie Camera" (Vertov, 1929) - Streaming for free on YouTube, Vertov's groundbreaking, experimental opus is another public domain freebie.

9. "The Passion of Joan of Arc" (Carl Theodor Dreyer, 1927) - Another one in the public domain, Dreyer's take on Joan of Arc is online for free at the Internet Archive.

10. "8 1/2" (Federico Fellini, 1963) - Rejoice, Netflix subscribers! 8 1/2 can be streamed on Netflix Instant. It's also free on Amazon Instant or can be rented for $8.50 $2.99.

  • Crackle

    <a href="http://paidcontent.org/article/419-draft-sonys-grouper-evolves-into-more-complex-video-package-rebrands-as/" target="_hplink">Crackle was bought by Sony in 2006</a> (when it was a startup called Grouper), and now its <a href="http://crackle.com" target="_hplink">streaming-only movie and TV library </a>features mostly Sony productions. It is free to watch, and you don't have to register, but you do have to sit through advertisements that break up your movie. The options are fairly limited right now--there are about 250 full-length movies and episodes from 50 TV shows, though apparently Crackle adds about 10 of each every month. The quality of the options is pretty good, however; I've been watching "Pineapple Express" since lunch, and I'm moving on to the original "Bad Boys" when that's done. The stream looks great at 480p on my laptop, though would probably pixellate on a television screen. <strong>PROS</strong>: Totally free, no registration required; varied quality options; user-friendly website design; good picture on laptop for free service; free iPhone, iPad and Android app. <strong>CONS</strong>: Ads, ads, ads; limited quantity of movies and especially TV shows; no DVD rental option.

  • Vudu

    A startup founded in 2004 and <a href="http://www.huffingtonpost.com/2010/02/23/walmart-vudu-deal-walmart_n_472838.html" target="_hplink">purchased by Wal-Mart</a> in 2010, <a href="http://vudu.com" target="_hplink">Vudu is a movie-streaming service</a> that prides itself on two key features: first, it has a database of high definition, 1080p movies that is larger than any other website's; and second, it is accessible on any device that connects to the Internet, from PlayStation 3s and Blu-Ray Players, to laptops and Internet-enabled TVs. Vudu is compatible with over 300 devices and works as a simple laptop movie streamer, too. The selection is terrific--over 20,000 movies are available-- though the payment option (for me) is not as terrific. Renting a movie for two days costs between $2 and $7, depending on the desirability of the movie and the streaming quality. A new release in high definition at $7 for 2 days? Pass. <strong>PROS</strong>: High definition streaming; terrific selection of new releases and classics; great "Collections" sections, including my personal favorite, a "Best of Rotten Tomatoes" playlist. <strong>CONS</strong>: Pay-per-view on-demand system can get very expensive very fast; no DVD rental.

  • Facets.org

    That ".org" is not a typo: <a href="http://www.facetsmovies.com/user/homeNewUser2.php" target="_hplink">Facets Multi-Media is a Chicago-based non-profit</a> founded in 1975 as a film appreciation group that now has a monthly DVD-by-mail rental system similar to Netflix's. There are over 75,000 movies in its warehouse, and one-out-at-a-time plans are $8.99 a month or $90 a year. If you're a little squeamish about signing up for a year, the monthly plan is one dollar more than the new Netflix DVD-only plan ($7.99), but perhaps you can justify the extra expense with the knowledge you're supporting a non-profit. As a film appreciation society, Facets has a great selection of rare and imported films, as well as playlists <a href="http://www.facetsmovies.com/user/moviePickExpert.php" target="_hplink">curated by "experts" that are worth checking out</a>. <strong>PROS:</strong> Reasonably priced DVD-by-mail rentals from a non-profit; excellent selection of independent and foreign films; recommendation lists from Werner Herzog, Stephen Sondheim, Dan Savage, and other notables. <strong>CONS:</strong> No streaming (yet--a company spokesperson says it's on its way); cannot match Netflix's prices, even after the price hike.

  • GreenCine

    <a href="http://greencine.com" target="_hplink">San Francisco-based GreenCine is Netflix for film buffs</a>; they have "an accent on independent, art house, classics, foreign, documentary, anime and Asian cinema," as their website <a href="http://www.greencine.com/central/dvdrentalinfo" target="_hplink">boasts</a>. With over 30,000 DVDs available for rent at plans starting at $9.95 per month (which lets you take out one video at a time), it's a little more expensive than Netflix for mail rental, but that is the price you pay for Greencine's "eclection" (again, per their website). Not included in your monthly fee are on-demand rentals: rather than streaming, you download the movie on DivX. Most of those rentals are $5 for 30 days with the DRM-protected flick. So, streaming is available, but only for a price. <strong>PROS:</strong> Awesome online selection of niche films, including anime, indie, and foreign; Blu-Rays available; DivX-quality watching on computer <strong>CONS:</strong> The prices. More expensive than Netflix, and the per-rental fee for streaming is way too high unless you are only streaming one movie a month
