After defeating Vandal Savage (Casper Crump) in Season 1, the second season of Legends of Tomorrow introduced a team of supervillains in the form of the Legion of Doom. Arrowverse actor Matt Letscher revealed the actors had so much fun working together on the show; they even pitched a Legion of Doom sitcom idea to The CW.
As most of you know, Letscher made his debut as Eobard Thawne, aka Reverse-Flash, on the first season of The Flash where the character (who was primarily played by Tom Cavanagh) was a major thorn in the side of the Fastest Man Alive until the show’s third season (sporadically showing up from Season 2 onwards). The character then crossed-over to Legends of Tomorrow during the time-traveling series’ second season when he put together the Legion of Doom; the villainous team made up of Arrow villains Damien Darhk (Neal McDonough) and Malcolm Merlyn (John Barrowman), as well as (albeit later in the game) The Flash’s Captain Cold (Wentworth Miller).
“It was a lot of fun,” Letscher said In a recent interview with Discussing Film about working on Legends of Tomorrow. “I had a great time with those guys. And you can tell they’re having fun, too. It’s definitely one of those sets that was really easy to work on, everybody was such a pro. We pitched – multiple times — we pitched a half-hour sitcom version of the Legion of Doom to the powers that be at CW and nobody’s bitten yet, but I still think there’s a possibility.”
Of the Legion members, only Damien Darhk is back on the third season of Legends after being resurrected by his daughter Nora (Courtney Ford). Malcolm Merlyn and Captain Cold were returned to the timelines they were plucked from at the end of Season 2 and are now currently dead, while Thawne was erased from existence by the Black Flash. Despite that, his time remnants are still preserved through history by the Speed Force (in order to stabilize the timeline and prevent more paradoxes), meaning he could still show up again at any time.
What worked with the Legion was that the actors and their characters had great chemistry together and played well against one another. They also brought a lot of villainous fun to the DC TV series where at some point they managed to alter reality (Doomworld, anyone?) and shrunk the Waverider, with Rip Hunter still inside. It was hilarious.
Also, since time travel is possible in the Arrowverse (as is resurrection), who knows? A Legion of Doom sitcom could theoretically still happen... and we'd watch that. How about you?
