Executive producer Marc Guggenheim teases what fans can expect in the fourth season of ‘Arrow.’

“We are already hard at work planning out the story arcs for season 4,” Guggenheim says. “You want to find out how team Arrow’s going to continue to save the city now that the Arrow has retired? Season 4 holds all the answers.”

In an interview with io9, Guggenheim revealed:

“It will take a lighter tone. That’s pretty much the only thing I say without spoiling it,” he said. “We’ve been working for about a month now in the writers’ room, talking about season 4, and I think that one thing we all collectively understood was season 3 beginning with Sara’s death, because it’s the death of a major character on the show, it set a tone for the remainder of the season. And I’m not the least bit apologetic for that tone. I happen to like dark and I like the fact that Arrow is a pretty dark show particularly for a network show. That said, every year you want to mix things up and there was sort of a collective desire on all of our parts to try to inject a little bit more lightness into the show, a little bit more humor. It’s not going to radically change. The show’s still going to be the show but in terms of tone we’re coming off a very very hard season for all of our characters. We wanted to try to mix it up a little bit.”
