Sounds awesome! But way too expensive for TV I think as well.
I'm holding out hope that down the road Marvel might take a break from the Avengers (maybe after phase 3 when the Big 3 have run their course) and tell some of those stories over a series of films.
Yeah, they would have to spend a lot on making sure the setting looks like 30s New York already and then would even have to waste more on the Human-Torch and Namor. It would certain rival A Game of Throne's Budget.
Then again i think there is another way around, like instead of focusing on all the Golden Age characters now and then they could focus on Phil Sheldon and the Angel, as well as focus on street crime while the films focus on the Human-Torch and Namor characters respectivelly, with some crossovers here and there.
This is an idea to expand upon the golden age if they make more movies set in that period, i was allways fascinated by this time and there's really a lot they could do.
ABC does have better ratings, so i bet they'dd be willing to give some money for a Marvel/ Disney show than HBO can, if they didn't want to make movies but were willing to give a Game of Thrones budget to a show like this the best way would probably to have the first season be around 7 episodes, maintaining the focus on these different characters but not exactly focusing on the action.
Namor would spend most of his time learning more about people from the world he plans to invade, Human-Torch just wants to be left alone but starts to get a hold of his powers, Phil Sheldon is our human in the show, from this guy we would see what people feel about the Marvels, and Angel is the one from which we learn about the underground world in the city, and the other people who put on a costume following the others example.
The show would Basically take from Marvels, The Marvel Project, the Marvel 75th annyversary issues released set that were set in the golden age, and the comics released during the golden age themselves. This show would certainly be a challenge but i'm sure if done, with the Human-Torch and Namor as featured characters or not, it could be something amazing.
