Christopher Walken
Bill Cosby
Richard Nixon
Humphrey Bogart
Arnold Schwarzenegger
Billy Dee Williams
Craig T. Nelson
John Wayne
Jeff Goldblum
John Elroy Sanford

Oh, and in case you're wondering, here's the whole list (in no particular order):

1) Humphrey Bogart
2) Dean Martin*
3) Robert Redford
4) Christopher Walken
5) Robert Deniro
6) Willem Defoe
7) Paul Newman
Al Pacino
9) James Dean
10) George Clooney**

*Some people would put Sinatra in the list as a representative of the Rat Pack, but I like Dean better. The voice was just as good, and he seemed not to be quite as enamored with himself.

**I mean, come on. Can all our wives, daughters, moms, and sisters be wrong? I think not. But that's not what gets him on the list. He makes the cut because even though they aren't wrong, I don't resent him for it.

The title indeed comes from a painting. The original artist was Edward Hopper and his painting "Nighthawks," was of a diner in Greenwich village:

That painting was adapted into "Boulevard of Broken Dreams," by Gottfried Helnwein and featured Marilyn Monroe, Humphrey Bogart, Elvis Presley and James Dean.
