More than other shows of its ilk, CW's Legends of Tomorrow excels because of the ebb and flow of its team cast, including the factor that some of them won't be around for seasons to come. That isn't necessarily restrained to death either, as both Hawkman and Hawkgirl left at the end of season 1. That same episode a new character debuted, but that formula won't be in force for season 2.
Executive producer Phil Klemmer recently spoke to ComicBook.com's Russ Burlingame about the season 2 finale, and while it will be epic in scope, it will not be a character tease like last time. "We won't meet any of the new cast or tease any of the new cast," Klemmer said. "It's difficult enough to come up with a new season of TV. When you have to sort of explain why Hourman was there, and why he disappeared and what happened to him, it can frankly make your head explode. The last 45 seconds of Legends will certainly contain a surprise, but adding characters to the finale would have been impossible. As you know from the end of the last episode, the plan is to go back and our 8 Legends become 16, and adding in the Legion of Doom, logistically, it's the most complicated episode I've ever been involved with. You have to watch it really carefully; there's some real time-travel farce in the episode."
Some of that was mitigated thanks to the experiences from the Invasion crossover. "When they're the same people, you don't even have the luxury of giving them the day off and saying, 'Okay, it's time to shoot Supergirl's scenes,'" Klemmer said of the challenges. "When you have multiple Legends, it becomes the same actors and it becomes technically very challenging. But the crossovers are for sure boot camp and once you've survived a crossover, it does sort of empower us to be like, 'oh, look. There's no way it can ever be that hard!' and then we somehow managed to make it harder for the finale."
