The Jan Hammer track "Crockett's Theme", arguably the most famous piece he composed for the show after the "Miami Vice Theme", makes its debut in this episode, in the scene where Crockett talks with Caroline on the beach at the safe house. The piece would become one of the hallmarks of the series, often featuring prominently, appropriately enough, in Crockett-centric episodes.
Professional assassin Ludovici Armstrong doesn't have any lines in this episode though he is a very central character.
-This marks the final appearance of Gregory Sierra as Lou Rodriguez. Sierra had requested to be written out of the show because he didn't like living in Miami (where the series was filmed).
Tito Goya, the actor who played Mendez, the Argentinean hitman's handler, was charged with murder shortly after his appearance, for his alleged involvement in a homicide together with his brother in 1978. Goya died in 1985 before he could be tried, but his brother was found guilty of the murder in question and was sentenced to 20 years in prison.
