If the world hadn't gone and got itself into a big, complicated mess, The Flash may have been extended on The CW for a couple more years. This, according to Grant Gustin, who stars as Barry Allen on the long-running DC Comics series. Even though the season 6 finale has yet to air, Gustin has revealed that talks to extend the show through season 9 were already happening before the production shutdown occurred.

Grant Gustin was recently a guest on Inside of You, Michael Rosenbaum's podcast. Rosenbaum was also a major part of a DC series, playing Lex Luthor on Smallville. During the course of the interview, Gustin explained that conversations with the network for season 8 and 9 had already begun, but have since been put on hold. Here's what he had to say about it.

"The conversations actually had started already for adding a potential eighth and ninth [season], but then this [situation] happened, and everything has stopped. We don't know when we're back, and I don't know when we're going to continue the renegotiation talks."

Setting aside the unknowns here, this is a fascinating bit of insight. The Flash has already been renewed for season 7, which was originally going to air during the fall. Again, with the shutdown, that may change but the important thing is that it was already on the table. The fact that The CW was looking to renegotiate for two additional seasons of the hit ArrowVerse series beyond that signals the confidence they have in keeping the ArrowVerse going for years to come.

Arrow, which kicked off this small screen version of the DC universe, recently ended its run after eight seasons. Assuming talks do resume once production picks back up, that means The Flash could potentially become the longest-running show in the ArrowVerse before all is said and done. That would be an undoubtedly impressive accomplishment.

But it's also important to note that these negotiations would be for a potential season 8 and season 9. It doesn't mean that they would for sure go ahead, it just means that Grant Gustin would have those options outlined in his contract, in addition to the rest of the core cast. The ensemble for the series also includes Candice Patton, Danielle Panabaker, Carlos Valdes, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.

The Flash, as well as many of the network's other shows, had to shorten their current seasons following the shutdown. The Supernatural series finale, for example, will need to be finished at a later date and has been delayed indefinitely. So when season 7 airs, it will presumably be picking up with the leftover storylines from the current season.The Flash season 6 finale is set to air on The CW on May 12.
