[1] Tony Leblanc was born on the grounds of the Museo del Prado at Madrid, where his family lived because of his father's employment as the museum's janitor.

Leblanc's decline began in the mid-70s, after theatrical hits like Paloma palomita palomera and Esta es mi vida (1975), when an old ailment was aggravated, leaving him semi-disabled and unable to continue his acting career.

A true pioneer of television in Spain in the 1950s and 1960s, Leblanc combined his cinema career with comedy specials, various comedic performances and a few programmes by Televisión Española such as Las Gomas (1956), La Goleta (1957), Gran Parada (1963–1964), El que dice ser y llamarse (1965), En órbita (1967), Cita con Tony Leblanc (1969) and Canción 71 (1971).

Following this, Segura convinced him to accept a role in his film Torrente (1998), which earned Leblanc a Goya Award for Best Supporting Actor.

From 2001 to 2008, Tony Leblanc appeared in Televisión Española's series Cuéntame cómo pasó for 181 episodes, in the supporting role of Cervan, an old and charming newsagent.

Tony Leblanc has also produced, directed and written several films, debuting as director of El pobre García, a comedy starring Lina Morgan and Manolo Gómez Bur.
