In the 1953 season star Duncan Renaldo was injured in a rock fall and hospitalized, resulting in his missing nine episodes. To cover for Renaldo's absence on the show, the Cisco Kid was shown wearing masks, disguised as a ghost and in other situations where a double could be used for him and footage of him that had been previously shot but not used was also used. He recorded his lines from his hospital bed.
This was the first television series to be shot in color. However, broadcasts were still in black and white at the time and few viewers saw the series in color until the 1960s.
