7. Arkham Asylum
There are many, many comic book arcs and limited series’ which could be used as inspiration for a TV show based on this iconic Gotham City location, but rather than regurgitate those to you here, here’s our pitch. It would likely have to be an eight-part series on a network like HBO (it’s hard to imagine anyone being able to successfully turn this into a 22-part episodic series), and that scrapped Supermax movie could be a great place to turn for inspiration. For those of you unfamiliar with that, it would have featured Green Arrow trying to battle his way out of a supervillain jail after being wrongly imprisoned, with the likes of Lex Luthor and The Joker all set to cameo. Now, imagine picking a character from the Batman corner of the DC Universe (Bruce Wayne, sans costume and gadget perhaps?) and placing them in a similar situation with everyone from The Riddler to Killer Croc and Mr. Freeze making their presence felt as the lead tries to escape the deadly institution?
