It's been the question dogging Hollywood since at least the first installment of Iron Man: when will the film business simply run out of super heroes to make into movies?

Together, Marvel and DC Comics, the top two comic book publishers in the industry,  have over 20 superhero movies scheduled to hit theatres between now and 2020. But studio chiefs are rightly worried that the super hero flick could just go the way of the Western.

Yes, this is a justified concern because even now, at times, it feels as though we've reached peak superhero anything. If there's one thing we know, however, it's that the genre won't go stale because Marvel and DC Comics run out of characters to transfer to the silver screen. Both publishers have over 75 year old comic book universes that are filled with characters waiting for their moment to shine in a live-action feature. The following is far from exhaustive—again, 75 year old histories—but, here are a few characters I would love to see in a film. 

Miles Morales, Spider-Man (Marvel)

Yes, we've had three Spider-Man movies. We've also had a reboot of that trilogy that led to a terrible sequel. And, it's rumored that Marvel and Sony plan to introduce a new Spider-Man in "Captain America: Civil War," with the ultimate goal of giving this new one his own solo film, thus giving us a reboot of a reboot. But, I stand by this suggestions because if there's one thing the superhero film industrial complex needs, it is diversity. 

For the uninitiated, Miles Morales, a black latino teenager from Brooklyn, is the Spider-Man of Marvel's Ultimate Universe. (Rather, he was until the Ultimate Universe, along with the normal one with which most are familiar, was destroyed in the publisher's epic summer-long crossover event "Secret Wars.") Miles took the Spidey-mantle when that universe's Peter Parker died in 2011 and has since gone on to become a fan favorite. In fact, once "Secret Wars" ends, it's expected that he'll join the All-New, All-Different Marvel Universe

When news broke that Sony and Marvel were teaming up to bring Spider-Man into the Marvel Cinematic Universe, fans hoped this would mean Miles. Unfortunately, in April, Marvel leader Kevin Feige confirmed that they are going with a teenaged Peter Parker. 

Kamala Khan, Ms. Marvel (Marvel)

In 2014, Marvel introduced the new Ms. Marvel, Kamala Khan, a Muslim-American teenager from New Jersey who developed shapeshifting powers after exposure to the Terrigen Mists. Taking over the name previously held by Carol Danvers, who now goes by Captain Marvel and will headline her own film in 2018, Khan became the publisher's first title headlined by a Muslim character. And, the book was loved by both critics and audiences. It's first collected volume was one of the top selling graphic novels in October 2014. If Marvel's looking to add some youth to its universe, they couldn't go wrong with this character, who some called the new Spider-Man. 

Batman Beyond (DC)

Debuting first on television in an animated series in 1999, Batman Beyond is the Batman of the future (the series took place mainly in 2039). At this point, Bruce Wayne is too old protect his city and has passed the Batman mantle down to Terry McGinnis, who is later revealed to have been created from Bruce's DNA and is his biological son. Terry's batsuit comes loaded with a host of great gadgets and features like invisibility and flight. Every movie has been about Bruce Wayne, and I'm not sure I can stand having to watch his parents die one more time. Moving the story to the future and changing who wears the cowl may be just what the franchise needs to freshen it up. If there's one thing the show's quasi-series finale taught us, it's that the world needs a Batman and a clone of the original will more than suffice. 

The Question (DC) 

The Question made his first appearance in 1967. The first incarnation of the character was named Vic Sage, who was a paranoid investigative reporter by day, and a vigilante who concealed his face with a blank facemask by night. (Rorschach from "Watchmen" is was based on  him). Later in the comics, Gotham City Police Detective Renee Montoya eventually becomes the new Question, but that ended when DC launched the New 52. Director Kevin Smith has even expressed interest in directing a "noir-ish thriller"about the character. 

Black Widow (Marvel)

You've seen the Marvel movies and know how awesome Black Widow is. It's time to give the character her own espionage film. 

Legion of Superheroes (DC)

The Legion of Superheroes is a team of young heroes from the 30th century. At some point, it was canon that young Kal-El travelled to the future and was a member of the legion.  It's a huge team, so not everyone in the comics would even fit in a movie. However, there are great members: Cosmic Boy (magnetism), Saturn Girl (telepathy), Lightning Lad, Bouncing Boy, and even Matter Eater lad, who can eat anything! 

She-Hulk (Marvel)

She-Hulk, a.k.a Jessica Walters, made her first appearance in 1980 as the lawyer cousin of Bruce Banner, who is also known as the Hulk. Jessica is permanently in her Hulk-state, but she also maintains her intelligencen and composure. Right now, the character is a member of the A-Force, an all female Avengers team whose series deubted in "Secret Wars." (ASIDE: An A-Force movie would also be awesome.) 

Animal Man (DC)

In the DC Universe, Animal Man, thanks to prolific comic book writer Grant Morrison, is one of the few heroes that's aware he's a fictional character. Imagine a meta supehero film about this character with the power to take on the abilites of any animal. It could be like the "Community" of superhero films where it's more concerned deconstructing the genre than sensory overloading CGI—because if there's one thing audiences love, it's a good old fashion deconstruction.   

Doctor Fate (DC)

In the interest of competition, a Doctor Fate film could be DC Comics' response to Marvel's "Doctor Strange," which scheduled to bow in November 2016 with Benedict Cumberbatch as the lead. As is the case with most DC heroes,  there have been several Doctor Fates; however, they all, for the most part, are all able to use magic thanks to three mystical items once owned by an Egyptian sorcerer: the Helmet of Fate, the Amulet of Anubis and the Cloak of Destiny. 

Namor (Marvel)

Introduced in 1939, Namor is one of the first mutants of the Marvel universe. Like DC's Aquaman, Namor the Sub-Mariner rules Atlantis. He has also a fairly tense relationship with the surface and, depending on what the story demands, can make for a great villain. Based on comments from Feige, however, it's doubtful that we'll see in him a movie anytime soon. 

Deadman (DC) 

Deadman is, well, dead. Boston Brand, a former circus trapeze artist, was murdered during his act. He was allowed to return the realm of the living as a ghost to avenge his death, but has stuck around because he has the power to possess any being. The character is particularly known for his humor and would probably work well in a black comedy.
