Ferrara demonstrated an interest in acting since he was a young child. But it wasn't until he was 22 that he booked his first job as an actor. He changed his name to Juan Ferrara before playing a small role in the 1965 movie, "Tajimara". In 1966, he got his first major movie role, as Sonny in Los Angeles de Puebla. Ferrara by then had graduated from Televisa's renowned acting school, and producers decided to cast him as a star in his own telenovela, El Espejismo Brillaba. The novela became a hit across Mexico and Latin America.[citation needed]
In 1970, he starred in two successful novelas, Yesenia and La Gata. In 1978, Ferrara was in Viviana, another extremely successful novela. He portrayed Julio Montesinos. In 1982 Ferrara then went on to star in Gabriel y Gabriela, though it was not as successful as his previous ventures.[citation needed]
1983 proved to be an important career year for Ferrara, as he established himself as an actor in Puerto Rico as well. Hired by Canal 2, he filmed Laura Guzman, Culpable!, a soap opera that became one of Puerto Rico's most seen television programs ever. Due to the novela's overwhelming popularity in Puerto Rico, the network decided to bring Ferrara back in 1985, to film a telenovela called Tanairi. Ferrara starred alongside Von Marie Mendez in this soap opera.[citation needed]
