Kreutzberger started a TV show in 1962, and he named it Sábados Gigantes on Canal 13. In it, he adapted many of the formulas he had seen in American television to the Chilean public. The show became an instant hit that had lasted over 53 years. In 1987, the show began to be produced by SIN in Los Angeles, California, with the same formula used in Chile, with the slightly different name of Sábado Gigante to KMEX-DT channel 34 Los Angeles. In the following six years Kreutzberger developed a three-hour-long variety show, including contests, comedy, interviews and a traveling camera section. The traveling camera, or Cámara Viajera (originally La Película Extranjera, The Foreign Movie), has taken "Don Francisco" to over 185 countries worldwide, many of them more than once. Kreutzberger in his show has interviewed many celebrities, including Roberto Durán, Cristina Saralegui, Sussan Taunton, Charytín, Bill Clinton, George W. Bush, Barack Obama, Bill Gates and many others. In addition, his show has launched the careers of famous entertainers, such as Lili Estefan, Sissi Fleitas, and numerous more. Kreutzberger appeared as himself in the movie The 33, about the 2010 Copiapó mining accident.
