Great Advertising Movies

Marketing industry icon/blogging hero Rick Bruner runs (among other things)
an email discussion list about ad research. A thread appeared just a while ago, about movies that feature advertising. The list is just too interesting to let fade, so here it is captured; I'll keep adding as the titles get mentioned. (add your own in comments):

Putney Swope: a classic cult flick that is waaay too politically incorrect.
The Hucksters: Sidney Greenstreet classic
How to get Ahead in Advertising: another odd little underground classic
Mr. Blandings Builds his Dream Home: Cary Grant!
