FRANCISCO CALVO GUIRAO, born on this date,  known professionally as Javier Calvo is a Spanish actor and filmmaker. He first achieved fame in Spain for his role of Fernando “Fer” Redondo in the television series Física o Química (2008–2011). Calvo and his former partner Javier Ambrossi began a professional partnership (widely known as ‘Los Javis’) by writing and directing the stage play La llamada, with its success leading to a film adaptation released in 2017. Calvo and Ambrossi later developed the television series Paquita Salas, Veneno (2020–2023) and its sequel Vestidas de azul (2023–2024), and La mesías, as well as the film La bola negra (2026). He has received several awards including wins in both the Feroz Awards and Fotogramas de Plata, and has received nominations for two Goya Awards. For the film La bola negra, Calvo and Ambrossi won the Cannes Film Festival Award for Best Director.

In 2012, Calvo started a relationship with actor and director Javier Ambrossi. The writer-director pair are popularly known as ‘Los Javis’. The couple shares a tattoo stating ‘Lo hacemos y ya vemos’ translating to ‘We’ll do it and we’ll see’. Calvo has an active social media presence, often changes his hairstyle, and collaborated with Ambrossi on the fashion line As If. ‘Los Javis’ have also claimed that early in the production of La llamada (the musical version), they had to purchase many stage props themselves, including two beds for 100 euros on eBay, despite having little finances at the time.

In November 2025, the couple announced their separation after 13 years together.
