Be warned, there will be heavy spoilers if you haven't seen last night's Arrow mid-season finale, "Three Ghosts", so read on at your own risk.

In his second Arrow episode as Barry Allen, Grant Gustin was struck by a bolt of lighting, which turned him into The Flash. The CW Network has released a video interview with the actor discussing his two-episode arc. Check out the video, then read on for a separate interview with the actor talking about The Flash spin-off series, along with executive producers Greg Berlanti, Andrew Kreisberg and Geoff Johns.

While his arc on the CW series ended with that episode, we reported last month that The Flash spin-off is now getting a traditional pilot, instead of the back-door pilot that that would have aired as the 20th Arrow Season 2 episode. Although the pilot script hasn't been completed yet, Grant Gustin revealed he's excited to learn what will happen next with The Flash.

"I'm mostly looking forward to getting the pilot script and seeing how Barry's going to handle this happening to him. He's not just excited. It's scary. That's what I loved about the character in the audition process -- it's not just he loves superheroes, and he's a fanboy, and all of a sudden he's like, "I'm going to be one, I'm really stoked about it." It's kind of like, 'This is terrifying. This is really happening to me.' I'm really excited to play more of that."

Greg Berlanti, Andrew Kreisberg and Geoff Johns wrote The Flash spin-off script, with David Nutter attached to direct. Although the character did debut on Arrow, Andrew Kreisberg revealed they plan on keeping both shows as separate as possible.

"We'll want to keep Arrow as distinctive as possible, and Flash as distinctive as possible. Part of the fun will be how those two things play out in both shows, if we get that opportunity."

Geoff Johns elaborated with the following statement.

"But there are story reasons that Flash feels different and that he's taking on different things in his series."

After just one and a half seasons, Arrow has already brought in a multitude of DC Comics characters, such as Brother Blood (Kevin Alejandro), Black Canary (Caity Lotz) and Bronze Tiger (Michael Jai White), just to name a few. When asked if the spin-off will follow the same format, Andrew Kreisberg had this to say.

"In the same way that Arrow was conducive to bringing on characters like Deadshot and the Huntress and some of the more grounded people, hopefully with The Flash there's a way to bring on some of the more fantastical characters, that will probably still go through the grounding lens with which we view everything. But we could tackle some of the bigger villains, and possibly heroes. There's a hint of a major character in the pilot. But it's always important to remember -- like with Arrow, everybody wants Batman to come on and whatnot, but Arrow has to be the coolest person on Arrow. The same thing with The Flash -- Barry has to be the coolest person. If we're lucky enough to get to do more past the pilot, it'll really be about making sure that the audience loves The Flash, and Barry Allen, and Grant Gustin, as much as we do."

While he wouldn't reveal specifics, Geoff Johns teased that there are several comic book characters they plan on using for The Flash.

"We're using a lot of mythology, a lot of characters from the comics in the development of The Flash show. I don't want to get too specific yet, but you'll see a lot of characters, a lot of elements from that. It's very much The Flash."
