As movie trailers go, 2010 was dominated on YouTube by two fantasy films, including the Twilight franchise's third film Twilight: Eclipse. The top viewed trailers for that film combined for over 30 million worldwide views this year. "Eclipse trailer" was also the top rising search on YouTube for March of this year. You can see the other top search terms here.

Below, you can find the most viewed trailers in the US. Interestingly, some of the films -- like Clash of the Titans and The Virginity Hit -- received nearly all of their views from the US, while others -- like The Expendables -- saw the bulk of their views come worldwide.

(It may take a moment for the chart to load in full.)

Below you can check out how things shook out in terms of global views. Perhaps the biggest difference on the list is the appearance of the trailer for Step Up 3D, which drew 8.03 million of its 9.23 million total views from outside the United States, predominantly in South and Southeast Asia. Thanks to a late run, the most recent installment in the Harry Potter series moved into the top spot globally ahead of Twilight.

The global list also contains a trailer for a movie that was never made...

Yep, a fan-made Pokemon trailer, which, for a time, left many people guessing about its authenticity, drew enough views to make our top 10 for 2010.
