Having taught Final Cut Pro for so long it wouldn't occur to me to open iMovie, but when one needs a pointless trailer for a pointless video, it's the program of choice. Can't beat spending 15 min. making it. Three cheers for iMovie. Don't make fun of me for using it.
As for the trailer, join in the powerful emotional journey as one man sits in front of a camera and rambles for 32 minutes.
