I think we should have a 2014 Casting Challenge, where we try and cast the show using actors and actresses that are the right age for a new show that starts filming in 2015. Starting with STORM FRONT, cast with Harry in his mid-twenties, Susan about the same, Murphy in her late twenties or early thirties, Michael old enough to have a a 12yo eldest daughter, Lea young enough to grow into her role without appearing to age over 10 years (so probably in her twenties, but looking worldly), etc, etc.
It seems hard. I've been looking for a good ~25yo actor for SF Harry, and I just haven't found one that's even remotely tall enough. It seems like a lot of actors these days are either well beneath 6', or big and beefy and playing Thor in in the movies.
