I've said before I'd love to see some standalone superhero movies set in the timeframe when the characters debuted (30s-40s for DC) (60's Marvel)
I loved the novel It's Superman by Tom DeHaven
This is a pretty neat concept, I may check it out
=============================
DC's Black Label imprint gives a graphic retelling of
Batman's origin, seamlessly blending 1930s vintage aesthetics with contemporary comic art and writing standards. This brutal, yet gorgeous rendition focuses on one of The Dark Knight's earliest mysteries, capturing "
The Bat-Man's" debut in Gotham. With its unique blend of dark vintage charm and modern storytelling, this comic series promises to be one of the best Batman stories in recent years.
The Bat-Man: First Knight #1, by the all-star team of Dan Jurgens, Mike Perkins, and Mike Spicer, is set against the backdrop of
a darker and grittier version of Gotham that is grappling with the aftermath of the First World War and the emergence of a brutal serial killer targeting city officials.
As this 1939 version of Batman investigates these grisly murders, he confronts a chilling twist: the evidence suggests that the perpetrators are men who have already met their demise in the electric chair. This sets the stage for a gripping tale of mystery with supernatural and noir elements...........
