So just on a whim I started watching The Rockford files. It's funny, witty, and as previously mentioned, holds up surprisingly well, when you make allowances for its age and time. Having been born in 1987, I'm enjoying the pure 70's-ness of it all. Especially the Detroit iron.
I noticed that when he is walking with a female acquaintance, even if it's a client he just met, he almost always leads them around by the arm, or with a hand on the back. I thought that might have just been the way they did things back then, but I haven't noticed that in any other films or tv shows.
Of course, when you're James Garner, maybe they just don't mind you doing that.
