What are some of the best movies about sales management?

Question

I have Glengary Glen Ross and Boiler Room. I'm looking for other films that have characters who are sales managers or plots about sales management. I am teaching a class in Sales Management and want to use a few good clips from some good films. My focus is sales management but the movie can be about team building, ethics, motivation or anythin else appropriate.

Answer 1

Tin Men is pretty good.
They are door-to-door aluminum siding salesmen.
What Women Want is good too.
