Of course, I would say this is possible but not assured casting, at least until a trade announces it or we see them at work.
Interesting choices certainly. I am guessing Nick Nolte is for World War (aka Jack and Ward's father), though there are a few other parts (like lawyer Weldon Pine) he could fit as well... though he's sort of too big a name for some perhaps. Macy is possibly Anita, the family housekeeper.
