i have been a long time Doc Savage fan and have been reading some of the later issues just recently. I also own a copy of the Ron Ely version which causes me to cringe thinking about what all might go wrong with the new movie. IF they play Doc Savage straight, show lots of 1930s toys (airships, autogyros, running boards, supermachine pistols, etc....), and don't make Pat Savage the real hero it could be great.
It definitely needs to stay in the 1930s (or make a slight shift towards DieselPunk). Bringing it in to the future was called Buckaroo Banzia.
