ABC's Whiskey Cavalier was a surprise, last-minute cancellation by ABC in May 2019, much to the consternation of a vocal contingent of loyal fans who felt the drama deserved more than a one-and-done. The cancellation was also surprising in that it had been touted as one of the big shows of the season for the network, featuring some hot stars and experienced showrunners. The network cited low ratings and not much room to grow in its decision. Distributor Warner Bros. attempted to shop it, but on 24 June 2019, David Hemingson announced the series was done.
Series trademark: each episode, the team travels to another country and a cover of a classic English-language song in that country's language is part of the episode's soundtrack.

Lauren Cohan and Tyler James Williams previously starred together in the fifth season of The Walking Dead (2010).
