Download iTunes movie trailers to your PC without Quicktime or iTunes
Update: The site link no longer works. Agent switcher extension for Firefox with useragent for iTunes will work. Refresh the movie trailer page and there should be a download link. If clicking the link does no download, copy the link to a new page to load.
I hate Quicktime and iTunes. Fortunately its possible to download iTune movie trailers without these bloated programs.

The guide using wget still works. Alternatively an easier method as mentioned in users' comments, use Firefox with agent switcher extension and set to "iTunes 6.5".
