[2][4] His debut in a feature film came with a performance in Carlos Romero Marchent's Oficio de muchachos [es],[3] released in 1986.

[6] On 8 September 2022 Cantó assumed the position of creative director at the television channel 7NN,[7] which stopped broadcasting on 31 March 2023 due to insufficient income to cover operating expenses.

4 days later, Cantó announced that he would sit as an independent and would seek the number two position on the Citizens' list for the 2015 Spanish general election.

[18] Following an ephemeral rapprochement with the Valencian government majority during the early stages of the COVID-19 pandemic, Cantó returned to an all-out style of opposition, going further than Vox and the PP in some stances.

[21] However, Cantó was registered in the Valencian Community (so he could run as a candidate in the Valencian regional election) and the electoral body is set by the national electoral law (LOREG) at two months before elections are called, so doubts were cast about Cantó's passive suffrage availability, as it requires active suffrage.

[22] In 2021, Cantó joined the Madrid-based ISSEP, a far-right educational centre founded in Spain by Marion Maréchal, to lecture on speaking skills.
