i just watched Helvetica. it's very well done and really entertaining, my favorite screen shot is shown here, a really wonderful skateboard design! (the film is really not like that, i probably picked the most controversial image possible.)
what i particularly liked about the film is that both sides are being heard: the helvetica fundamentalists who think that typefaces should be neutral and that legibility is of utmost importance and that helvetica is the way. and on the other hand the designers who think that typeface should be specific for a job and that the ubiquity of helvetica calls for a bit more variety, but of course sometimes overdoing it.
what i missed was a bit more context. the film nicely describes helvetica's history and how designers felt about it during various trends in the designer world (and i for my part am very happy that the
grunge design phase is over now). but the film only very briefly mentions Arial and does not even mention the whole issue around how to make money with typefaces. and the film also does not mention more modern fonts, such as Univers, which do have some success and simply are not as widespread because you don't get them for free on your mac...
