Mad Men people now working on Halt and Catch Fire
I just heard recently some MM writers have been writing for HACF, which makes a lot of sense,
Haven't yet found out which ones, since I'm unfamiliar with their names, excepting MW.
I did just discover MM's Michael Saltzman, who co-produced many of my favorite MM episodes, has been busy co-producing many HACF episodes.
There's a lot of Mad Menesque subtly, and showing vs telling.
