Soon after Supergirl's first season concluded on CBS it was announced that the show would air its sophomore run on The CW. This gave the network an unprecedented four DC television series, all contained within the same multiverse. Immediately, discussions turned to what type of crossover we could see now that Arrow, The Flash, Legends of Tomorrow, and Supergirl all call the same network home. And sure enough, news dropped that characters from all four series would unite in a massive three-part crossover, and that The Flash and Supergirl will have another crossover - this time with some added flare.
This second crossover will be a musical, which makes sense given that the two series' stars, Melissa Benoist and Grant Gustin, are both alumni of Fox's Glee. Further, Jesse L. Martin (Joe West), Jeremy Jordan (Winn Schott) and Carlos Valdes (Cisco Ramon) are all Broadway vets. While there is not much confirmed regarding the musical, it is natural to wonder whether any other Arrowverse stars will be chiming in. Perhaps the most accomplished vocalist in the entire multiverse resides on Legends of Tomorrow, And it looks like he may be getting ready to clear his voice.
Comic Book is reporting that Broadway veteran, Victor Garber, who stars on Legends of Tomorrow as Martin Stein, one half of Firestorm, may be joining the musical crossover as well. Executive producer, Greg Berlanti, spoke during a party celebrating Arrow's 100th episode, and he had this to say regarding Garber joining the crossover: "Oh, I'd be crazy not to... He's got one of the best voices. He actually sang for me at an event once, and if I ever get married, I'd have him sing at the wedding."
Given the decision to produce an Arrowverse musical, it only makes sense that Garber would be a considered addition. After all, the veteran of the stage has been a part of over a dozen Broadway musicals, and has earned several Tony Award nominations. As for the crossover itself, plot details remain thin. All that is known is that the event will take place near the end of the season, and will have nothing to do with aforementioned three-part crossover that will pit the heroes against the Dominators.
Even if Garber does not join the musical, however, Arrowverse fans still were able to see the actor's vocal proweress on display in a recent episode of Legends of Tomorrow. In the episode, Martin Stein posed as a famous Nazi vocalist, and proceeded to serenade the crowd - that is, until a fight broke out.
Supergirl airs Mondays at 8pm on The CW, The Flash airs in the same timeslot on Tuesdays, Arrow on Wednesdays, and Legends of Tomorrow on Thursdays.
