His European/Scandinavia heritage notwithstanding, actor Martin Garralaga was most effectively cast in Latin American roles. Many of his screen appearances were uncredited, but in 1944 he was awarded co-starring status in a series of Cisco Kid westerns produced at Monogram. Duncan Renaldo starred as Cisco, with Garralaga as comic sidekick Pancho. In 1946, Monogram producer Scott R. Dunlap realigned the Cisco Kid series; Renaldo remained in the lead, but now Garralaga's character name changed from picture to picture, and sometimes he showed up as the villain. Eventually Garralaga was replaced altogether by Leo Carrillo, who revived the Pancho character. Outside of his many westerns, Martin Garralaga could be seen in many wartime films with foreign settings; he shows up as a headwaiter in the 1942 classic Casablanca.
