I wonder if these maddicts are aware of Peter Gunn on RetroTV (check your local listings). This is an excellent primary source of retro style and suavity.
Peter Gunn and Lt. Jacoby (Gunn's friend and foil) hunt trouble in a world of noir chiaroscuro. Harsh neon light flashes on rain-slicked streets and through the windows of cheap hotels, where people are usually hiding from the Mob. Gunn is impeccable in his charcoal-gray suit; Jacoby, much less so. (He's the foil, remember?) And both of them stay poker-faced all the time.
Maddicts, don't blow your wad on one TV show! There's a whole world of historical TV out there to explore and live vacariously through.
