In Season 3, Brandon Routh suggests that the Legends should go to the Titantic because he heard that the food was great. Victor Garber replies that "there is no way that I step foot on the Titanic. Whoever designed the Titanic should be taken out and shot." Victor Garber portrayed Thomas Andrews, the Northern Irish engineer and ship builder who designed the Titanic in the 1997 James Cameron film.
Brandon Routh (Ray Palmer) and Courtney Ford (Nora Darkh) are married and have a child in real life.
Wentworth Miller and Dominic Purcell are both reprising their roles as Captain Cold and Heatwave from Flash (2014). They are known for being the two main characters and brothers in the hit TV-series Prison Break: Em Busca da Verdade (2005).
Throughout the series, Mick Rory assigns nicknames to his associates: Hawkman is "Birdman", the Flash is called "Red", Atom is called "Haircut", Green Arrow is "Robin Hood", Rip Hunter is "Englishman", and Supergirl is "Skirt'.
In the third episode, Rip Hunter says, "I've seen Men of Steel die and Dark Knights fall." This is a reference to the storylines The Death of Superman and Batman: Knightfall.
