Actress Norma Bengell, born in 1935 in Rio de Janeiro, appeared in 50 foreign films. This was her only appearance in a TV series in the U.S.
Two versions of this pilot exist. Two differences are evident, one major and one minor. The minor difference involves a snipped bit of dialog between Pepe and Cat, as they tell Pepe's daughter that each had at one time saved the other's life. The major difference involves the next to last scene. In both versions Capt McCallister gets injured. In the unaired version, Cat visits a bedridden McCallister and informs McCallister that Smith died at the hands of his mob superiors after he failed to kill the priest. In the aired version McCallister meets up with Cat at the Casa del Gato, and after Cat inquires of his recovery, asking if he's well enough to be there, McCallister tells Cat the info about Smith's fate.
