The big ArrowVerse crossover has become an annual event, but one show won't be taking part this year.
DC's Legends of Tomorrow won't dedicate an episode to the next multi-show event, which is set to introduce the character of Batwoman.
"We're not in the crossover this year - Legends are not in them at all," Caity Lotz, who plays Sara Lance, confirmed to media including Digital Spy at San Diego Comic-Con. "We're doing our own thing."
"There's another show that's gonna get launched and it just became over capacity," Legends showrunner Phil Klemmer explained.
"Our show is very, very difficult [to produce]... there are no easy episodes, everything pushes production and post-production and our actors to the absolute brink of exhaustion, and we frankly reached a breaking point."
Klemmer also pointed out that dedicating an episode to a crossover affects Legends more profoundly than the other ArrowVerse shows, since it has shorter seasons.
"We only have 16 episodes," he said. "So for us, we love the crossover, but it was aways a tonal speed-bump, or a departure, and we just don't have time to step away from our story this year."
The fourth season of Legends of Tomorrow will launch October 22 on The CW in the US. The series airs on Sky One in the UK.
