There's a movie called Objectified.
Objectified: A Documentary Film by Gary Hustwit

And it's all about design. And how people perceive products in a few seconds about their design. And how in these few seconds people make so many assumptions about the product in a few seconds.

And in this movie Jonathan Ive as well as a lot of others talk a lot about the product design process. The film is a little geeky. But I really think Ive is the genius behind Apple. Well one of them. And hearing his and others perspectives on the subject looks interesting.

The previous film by the same director is called "Helvetica"
And as you can probably guess, it's about typography and print design.
