As Marvel Entertainment have continued to flesh out their motion picture universe, DC Comics has been notably silent. The story goes that Green Lantern was the intended vanguard of a Justice League project mimicking Marvel's Avengers films with The Flash and Wonder Woman to follow. When the Ryan Reynolds vehicle failed to grab movie goers, it was back to square one. That could change is next year's Superman movie by Zack '300/Watchmen' Snyder is a blockbuster hit but in the meantime, this odd rumor has surfaced.

Both Marvel and DC have a stable of horror/supernatural characters, but both Swamp Thing and John Constantine (along with Neil Gaiman's version of Sandman) have long acted as tentpoles for DC's edgy Vertigo imprint targeting a more sophisticated audience. Forget that both Swamp Thing and Constantine have already been adapted as dire motion pictures as it is possible that Guillermo Del Toro could be stepping up to make a comic book movie unlike any that we have seen to date.

When the New 52 launched, an unlikely title brought the supernatural characters of the DCU together in Justice League Dark. This could be the inspiration behind the 'next big thing.' Combining these cult characters that appeal to a different demographic than those attending Avengers screening may be just the thing we need, especially when it is directed by Del Toro, who made the obscure hero Hellboy a household name.

(never mind that Del Toro's name gets attached to roughly a dozen projects each year that never see the light of day)

... or it could all be false rumor.

The New 52 series Justice League Dark could be the inspiration for DC's 'Heaven Sent'

Via Comicbook.com:

Take this rumor with a huge grain of salt–it sounds an awful lot like a pipe dream.

According to a rumor coming out of Latino Review, Hellboy and Pacific Rim director Guillermo del Toro is in negotiations with Warner Brothers to direct a film that, at least as it's described, sounds quite a bit like a Justice League Dark movie, even if there's no indication that it will be titled as such.

Actually reportedly titled Heaven Sent, the DC Comics movie will reportedly star Swamp Thing, Hellblazer, The Spectre and more.

According to the report, "[del Toro] does want to do his own version of the Avengers, just supernaturally. Called Heaven Sent, he is combining all the magical beings from DC Comics in one epic adventure. Deadman, The Spectre, Swamp Thing, Constantine Hellblazer, Phantom Stranger, Zatanna, Zatara, and Sargon as well as Etrigan the Demon will team up to no doubt save us from the Stay Puft Marshmallow man. Now this one is a ways away, but Warner's lawyers have been working every night trying to clear the rights to all these characters."

Why would they need to clear the rights, when Warner has owned DC free and clear for a number of years? Well, around the same time they were shopping around Arrow and the Booster Gold series that Syfy is developing, Warner Brothers and DC Entertainment optioned the rights to The Spectre to Fox for TV and The CW was looking into making something out of Deadman.

Swamp Thing from DC's highly acclaimed New 52

Notably absent from this rumor is Amethyst of Gemworld, who has her own series that just launched and has been featured on animated shorts during Cartoon Network's (currently suspended) DC Nation block. Whether that could mean they're developing the character on a separate track is unclear.

Two of these characters–Swamp Thing and John Constantine–have starred in their own feature films in the past.
