An international trailer for the stop-motion animated film ParaNorman has gone online.  The movie centers on a young boy named Norman (voiced by Let Me In's Kodi Smit-McPhee) who is able to see ghosts but it's no big deal.  It becomes a bigger deal when his small town comes under attack from the un-dead and he must save the day by stopping a centuries-old curse.  The US teaser trailer is one of my favorite trailers of the year, and the international version is also good, but it's more focused on introducing Norman and the plot.  The movie still looks like a lot of fun and it will be one worth keeping an eye on in 2012.Hit the jump to check out the trailer.  The film also features the voices of Casey Affleck, Anna Kendrick, Christopher Mintz-Plasse, Leslie Mann, Jeff Garlin, John Goodman, and Alex Borstein. ParaNorman opens in the US on August 17, 2012; it opens in the UK on September 14, 2012.Trailer via MSN UK.
