Arrow and DC's Legends of Tomorrow co-stars Brandon Routh and Caity Lotz appear together in a new trailer for 400 Days, which you can check out below.
Since their characters never interacted on Arrow, 400 Days and Legends are the first examples of the pair actually sharing screen time.
The forthcoming film from Syfy also features comedian and actor Dane Cook.
400 Days centers on four astronauts sent on a simulated mission to a distant planet to test the psychological effects of deep space travel. Locked away for 400 days, the crew's mental state begins to deteriorate when they lose all communication with the outside world. Forced to exit the ship, they discover that this mission may not have been a simulation after all.
