Nothing to a similar subject as design. I recommend "I Will Teach You To Be Rich" and "4 Hour Work Week" a lot. They're not design books, they're all about human psychology and implementation. These traits are what made "Don't Make Me Think" stand out to me. I Will Teach You To Be Rich is a quick read with things you can implement right away. 4 Hour Work Week is longer, it reads as a story, but has detailed information about product testing (skip to these sections if the motivation part doesn't interest you).

I watched Objectified, design movie. It was okay, but didn't give me much more than Don't Make Me Think. It probably would have made more of an impact if I watched it before reading the book. What these books/movies do is change your perception of the world. Once that's done and you see something similar you'd be like "of course" instead of "I never thought of it that way".
