The Flash's sixth season, which is currently airing, started with The Flash and his wife Iris West-Allen dealing with the loss of their daughter, and the most recent episode features Kid Flash's return to Central City.

And while season six isn't due to conclude until May, fans are already clamoring for details about the show's seventh season. The CW renewed The Flash way back in January, and if the show follows its previous production schedule, filming should start in July.

Here's what you need to know about season 7 of The Flash.

When will season 7 of The Flash premiere?

We can expect to see the seventh season of The Flash in early October. The six previous seasons of the show have premiered somewhere between October 4-10, and we can expect to see around the same for season 7.

Is there a season 7 trailer I can watch?

Not yet! While The Flash has been renewed for season 7, filming hasn't started yet. You can watch the show's season 6 trailer though, as there's still much more of The Flash to come.

Who will be in The Flash's cast for season 7?

We can expect to see Grant Gustin return in his lead role as The Flash, and Candice Patton and Danielle Panabaker will almost certainly reprise their roles as Iris West-Allen and Caitlin Snow/Killer Frost.

Rounding out the main cast will be Carlos Valdes as Cisco Ramon/Vibe, Tom Cavanagh as Harrison Wells, and Jesse L. Martin as Joe West. Less is known about the new characters that were introduced in season 6, including LaMonica Garrett as The Anti-Monitor and Efrat Dor as Eva McCulloch.

However, it's also possible that The Flash's seventh season could be its last. Last year, Gustin told Digital Spy that, "We're all contracted right now [for] seven seasonsthis is the sixth, so it's definitely in the back of my mind that next year, even, could be potentially the last season. Who knows?"
