"The Flash" is one of the most anticipated new debuts of the upcoming television season on the CW, and there's undoubtedly a lot of pressure to deliver a show with the same success rate as "Arrow." However, "The Flash" has a lot going for it -- in addition to star Grant Gustin getting introduced as Barry Allen during "Arrow" season two, "The Flash" shares some of the behind-the-scenes talent responsible for "Arrow's" success: executive producers Andrew Kreisberg and Greg Berlanti.

To help shed some light on the expectations and tone for the upcoming show, Kreisberg and Berlanti joined CBR executive producer Jonah Weiland on the CBR Yacht at Comic-Con International 2014, giving a behind-the-scenes look at "The Flash" and the potential it has in conjunction with "Arrow."

On the expectations for "The Flash": "We've always been the beneficiary of low expectations, so it's an odd sensation now," said Kreisberg. "But we're fans first. If we weren't being interviewed, we'd be out there [at Comic-Con]. We try to make a show for ourselves, a show that we would want to see, and hopefully, people come along for it. Right now, we're just really proud of what we've done and the work that all the actors have done, the visual effects -- and hopefully, the audience will respond the same way they have to 'Arrow.'"

On the more hopeful tone of the series: "That was definitely the intention," said Berlanti. "Though you're never sure how well you're going to execute it. It was the intention in large part because Barry Allen was a brighter character. There was an optimism, there was a comedic voice -- and we certainly thought about it in terms of wanting it to be different from 'Arrow,' but Barry's at the center of it. The tone of the show tends to reflect the character. Whereas, Oliver was very much one of DC Godlike, stern and taciturn kind of characters. Barry wasn't. He was one of us and we were really happy to create a world that reflected that.

On the cohesiveness of the DC Comics television universe: "Grant [Gustin] made such a strong impact on 'Arrow' and especially his relationship with Felicity -- there are things we feel like we have to pay off," said Kreisberg. "So, we have Emily Bett Rickards coming on in [the fourth episode] of 'The Flash.' For us, those crossover episodes -- whether it was those ones when we were kids or more recently like 'Buffy' or 'Angel'; 'Doctor Who' and 'Torchwood' and 'Sarah Jane' -- those were some of our most favorite episodes when both casts and everyone comes together. We figured, why wait? Let's get to the good stuff now."

"I also think the comic books have that," said Berlanti. "When I was a kid, one of the first things I would do when I read a comic book was to flip through really quick to see who showed up from other worlds, and it's nice to have that unpredictability. In this day and age when everything is so predictable sometimes on TV, that unpredictability of the world getting larger or contracting depending on the episode is nice for the audience."
