I believe the only reason "Glengarry Glen Ross" languishes in obscurity is because of its name.
I've watched the movie at least 50 times and I only have a vague theory as to why David Mamet may have selected this enigmatic title. But if it were to be punched up, if the title had a real hook to it, why, then it would be a film you could recommend indiscriminately to all of your friends and family. Right now when I tell someone they need to see GGGR I universally receive the blankest stare I've ever seen in my life, and then they change the subject as fast as physics will allow.
But I need help, so far I've only been able to come up with the following dismal titles. Please post a title that is worthy to present to David Mamet as a significant improvement on the original.
"Salesmen in Action"
"Shelly Makes Good"
"Shelly Gets Well"
