The Tower isn't just a home base for Team Supergirl. J'onn took some of the Arrowverse's other heroes into consideration when building the space. He placed several call buttons on the wall, with direct lines to Supergirl, Batwoman, the Flash, Dreamer, Brainy and himself.
Lex refers to Toyman as "Toyboy," a reference to Action Comics #837 (May, 2006). The Toyboy was an android created by Winslow Schott, the original Toyman. It briefly allied itself with Lex Luthor while searching for its creator, whom it later found. The robot originally went by the name "Toyman" but relinquished the name to Schott when they were reunited and took the new name "Toyboy." Since then, he has been deactivated.
For the epic "Eye of the Tiger" needle drop in the big climactic action scene with actual tigers, David Harewood was all in for it. "As soon as I read [the script], I was like, 'I've gotta do this!'" he says with a laugh. "It was a big challenge. We had to shoot that entire sequence in one day, we had to get creative. I was delighted when they gave me 'Eye of the Tiger' because I knew it was just going to be fun. It was a tough day, and we got everything with literally two minutes to spare. We only had that location for one day so I knew I had to crack on, and everyone was brilliant. I'm very proud of it."
