Arrow showrunner, Marc Guggenheim spoke to SuperHeroHype about the episode featuring Constantine in season 4.

Could Sarab Be Resuscitated In Season 4?  

Guggenheim dished that Constantine will be very naturally portrayed in the episode and will fit in very neatly into the realm of Arrow. The showrunner was all hype about the episode, stating that people are really going to love this one.

Here's Guggenheim's lowdown:

Green Lantern To Join 'Arrow' Crew In Season 4?  

"When you see him in the show, honestly it feels like we're doing a Constantine/Arrow crossover, and it's so exciting... We're just really glad we got the chance to extend Matt Ryan's run as Constantine by at least one more hour of television. I think you'll see he fits very neatly into our universe. It never feels forced, it feels right. Stephen's on-screen vibe with Matt is just very natural, it's as if these guys had been working together forever. I think people are really going to love the episode. John Badham (WarGames, Saturday Night Fever) directed it and it was just a happy circumstance, but John had also directed an episode of Constantine. It all works, and it works really effortlessly. It worked effortlessly with a lot of effort, I should say. I can't wait for people to see that episode. If you thought it was a thrill just to see that one shot of Matt in the trailer, wait til you see a whole episode with him."

Season 4 of Arrow will premiere on Oct. 7.
