The Flash has unleashed a hectic new trailer ahead of the return of its new episodes next month, with season 8B looking to be crammed with returning heroes and villains.

Although just one minute in length (and viewable above), fans have a great deal to digest in the new clip, as the likes of Impulse, XS, Eddie Thawne and gangster Goldface all make their presence felt.

"The family of speedsters is coming back to save the day," the official Flash account tweeted alongside the new teaser trailer, and it's fair to say there's a lot of high-speed spinning plates here.

When we last caught up with The Flash crew, they were busy saving the world (again) in the Arrowverse's recent five-headed 'Armageddon' event, which ended with Barry (Grant Gustin) and Iris' (Candice Patton) super-powered kids from the future appearing in the background of a CCPD photo from 2014.

And it looks like the consequences of Bart/Impulse (Jordan Fisher) and Nora/XS's (Jessica Parker Kennedy) appearance in the past will have a big impact on the timeline.

"Oh my god, the whole timeline's in flux," Nora warns in the trailer.

Meanwhile, Mia Queen actress Kat McNamara shared her hopes for another return sometime in the future.

"I would love nothing more than to come play in the Arrowverse again. Truly, if anybody needs a gal to come shoot some arrows at some bad guys in a cool supersuit, just cast a green arrow in the sky and I'll come running," she said ahead of her return in the final part of The Flash's huge crossover event.

"That was the biggest gift, I think, on this episode [Part 5]: that we didn't know whether Mia could come back or what happened or where the mythology stood on that, and Eric [Wallace] and the Flash writers were so wonderful to leave that door open and to make it possible for her to be a part of this world again.

"It's really an honour, and now maybe there's a potential for a future there," she pointed out.

Elsewhere in The Flash zone, the Worlds of DC version's upcoming solo flick confirmed the involvement of Man of Steel stars Michael Shannon and Antje Traue last month.

With The Flash releasing a first look at how the movie will set up the DC multiverse last year, it looks like we can expect to see a lot of familiar faces to return in the upcoming movie too.

The Flash season 8B premieres Wednesday, March 9 on The CW in the US. Sky Showcase and NOW air the show in the UK.
