Constantine
Matt Ryan will play John Constantine in NBC's "Constantine," an adaptation of the "Hellblazer" comic series. Which other comic book characters will NBC bring to life? NBC

NBC’s adaptation of the “Hellblazer” comic series will premiere this fall as “Constantine,” but not every character will make the jump from page to screen. Which characters will make the transition? See the list below to find out:

John Constantine: Matt Ryan will rock lead character's signature trench coat when he plays the title character. However, other signature touches haven’t been retained in the TV version of the comic series. The show's creators recently said they would not explore Constantine's bisexuality, but they did say they are trying hard to keep Constantine’s smoking habit in the show.

Chas Chandler – Charles Halford will step into the role of Constantine’s best friend. He functions as a sometime sidekick and cab driver for the demon hunter.

Zed – Angélica Celaya was announced as a cast member at the Television Critics Association summer press tour on July 13. Celaya’s Zed will replace Liv, a character who was created just for the show. Zed played Constantine’s feisty psychic girlfriend in the comics.

Papa Midnite – While not confirmed by the show's writers, Bleeding Cool reported that this character will appear in the pilot episode. Papa Midnite is an immortal mobster who uses voodoo to bring the dead back to life.

Jim Corrigan/The Spectre – Currently, this is just an idea that’s in the writers' room, but not necessarily the show. “Within the context of episode five, we had a need for a police officer who sees that supernatural evils exist,” showrunner Daniel Cerone told IGN. “Right there, okay, that’s an opportunity to introduce a DC character. So we talked to our DC representatives, and we’re, like, what if we make this character Jim Corrigan, who goes on the become The Spectre?”

One major change is where the show's story takes place. Whereas the comic series took place across the pond, "Constantine" will stay stateside for the TV show, and the pilot will take place in New York.

"Constantine" will premiere on NBC Friday, Oct. 24, at 10 p.m. EDT.
