As Legends of Tomorrow prepares to wrap its fifth season next week, co-creator and executive producer Marc Guggenheim confirmed preproduction is already underway on its sixth season.

While deferring to producers Phil Klemmer, Keto Shimizu and Grainne Godfree on how the COVID-19 pandemic would impact production itself, Guggenheim praised the story ideas for the next season as they are being developed.

"I will say that, during the pandemic, the writers have been working and they've been generating story documents and the story documents are awesome and they're hysterical," explained Guggenheim in an exclusive interview with CBR. "The writers are not impacted — the stories are not impacted by the pandemic."

The CW renewed Legends of Tomorrow for a sixth season this past January, weeks before the Season 5 premiere. Following the outbreak in North America, the network set the Season 6 premiere for mid-season 2021, and Guggenheim remains optimistic about the series' future.

"I think that that's kind of the philosophy that Legends has always taken, which is that the idea and the story and the characters come first and then the logistical feasibility of pulling something off, that becomes very last," reflected Guggenheim. "That's just as true with Season 6, in large part also because no one knows exactly how and when production will resume and what limitations there will be. But I think if you can try to get ahead of it, you end up closing doors that would otherwise remain open."

Airing Tuesdays at 9 p.m. ET/PT on The CW, DC's Legends of Tomorrow stars Caity Lotz, Dominic Purcell, Nick Zano, Maisie Richardson-Sellers, Tala Ashe, Matt Ryan and Jes Macallan.
