If you haven't seen the documentary on Helvetica yet, you're missing out. Last year I was able to attend a screening of the film and a Q&A session with the director Gary Hustwit and famous type designer Matthew Carter.
The documentary takes an in depth look at the evolution of the typeface, but it also includes interviews with top designers from around the world and their opinions about the role of typography and design for today's society. It was interesting to hear both sides of the debate about Helvetica, why some people love it and some people hate it. The film is a must-see if you are a designer or are just interested in learning more about design and typography.
