Grant Gustin and Stephen Amell

There’s another crossover between “Arrow” and “The Flash” coming and the two shows are aiming for an even bigger and better event than last season. With “Legends of Tomorrow” coming later in the season, there’s lots of work to be done and “Arrow” star Stephen Amell (Oliver Queen) says it’s going to lead to a very different viewing experience.

“Last year was designed so that if you were a fan of one show or a fan of the other show, you could enjoy 108 of ‘Flash’ and 308 of ‘Arrow’ independent of one another,” he tells Zap2it and a group of other outlets during a visit to the set of “Arrow.” It’s not the case this year. If you put them back to back on one night, they would run like one two-hour episode of television.”

The actor continues, “In fact, most of the ‘Flash’ episode takes place in Star City, and most of the ‘Arrow’ episode takes place in Central City. We have a common villain, which was not the case last year, and just in general, we’ve done an excellent job of weaving not just two shows, but three shows together.”

“Arrow” and “The Flash” executive producer Andrew Kreisberg, speaking at a screening of the Oct. 27 episode of “The Flash,” adds, “Just conceptually speaking, one of the ways we thought of these episodes, in sort of a macro sense, was that ‘The Flash’ episode this year plays more like an episode of ‘Arrow’ and the ‘Arrow’ episode plays more like an episode of ‘Flash.’”

“We look back and thought that those ‘Flash’ and ‘Arrow’ episodes were the biggest things we’d ever done,” Kreisberg says. “Now we have more heroes, more people with powers, more mouths to feed and bigger villains. It’s really exciting.”

While most of the crossover event has already been filmed, Amell reveals “there’s little pieces here and there to grab” before it’s officially wrapped. “I think these crossover episodes standing together will probably be, in my mind, the pinnacle achievement for both shows,” he says.

While Amell was careful not to reveal any huge details about what will go down in the crossover, he did spill one very interesting little tidbit.

“We shot a scene that had, like, nine superheroes in it,” he teases. “Nine people with either powers or super suits.”

“It was an amazing thing to look at, to look out over the scene and see the world that has been built over the course of three-plus years,” he says.
