My guess for Downton Abbey is that you are one of two extremes. You either LOVE Downton Abbey and can not wait for the feature film...or you've never seen a second of the show and would sooner stare at a wall, watching the paint dry. If you are the previous, then get all jazzed up, because we now have the trailer for the film, based on the British historical period drama that anglophiles could not get enough of.
The film is scheduled to be released in the United Kingdom on September 13th, followed by here in the US on September 20th.
