Helvetica: the Film
Yep, it's a documentary about a typeface! As Helvetica approaches it's 50th birthday, a small group got together to make a film about it. Looks like they've lined up a number of good people (Hermann Zapf is interviewed) and the stills look cool. They list a festival release of "early 2007".
Also, thanks to freakylynx for pointing to Spin [YouTube link].
This is a short film that came out a while back, evidently. It's a really well done piece; excellent use of sound and editing. Definitely worth checking out if you haven't seen it.
