To download the movie, first go to the movie’s vimeo page (https://vimeo.com/77248030).
Next, click the download button underneath the movie:
Some links will appear, allowing you to download the movie in either HD or SD (I would of course prefer that you watch the movie in HD, although it’s up to you). Click on one of the download links that appears to download the movie. On most computers you can just left-click the link and it’ll start downloading, but, if doesn’t work for you, try right-click->save-as to get it going.
