López became interested in filmmaking at a young age. After reading
Rebel Without a Crew (1995) by Robert Rodriguez and watching
Clerks (1994) by Kevin Smith, he began experimenting with his family's video camera. By the age of 12, he was already writing a column for
El Mercurio. His column,
Memorias de un Pingüino ("Memories of a Penguin"), ran from 1997 to 1999. Following his expulsion from school, he began writing a new column titled
López. He later co-wrote and produced
The Green Inferno (2013), which screened at festivals including Toronto and Sitges, and
Knock Knock (2015), starring Keanu Reeves and Ana de Armas, which premiered at the Sundance Film Festival. López also served as executive producer on
The Stranger (2014) and
The Inhabitant (2018), both directed by Guillermo Amoedo, and co-produced the Chilean films
Fuerzas Especiales (2014) and
Fuerzas Especiales 2 (2015), which together surpassed 400,000 admissions in Chile. The film was later included in a 2025 national survey by Cadem as the third most popular Chilean film of the previous decade. He followed with
Hazlo como hombre (2017), which grossed approximately $13.6 million worldwide and surpassed 4.2 million admissions in Mexico, becoming the highest-grossing Mexican film of its year. As co-producer, he participated in
Ya veremos (2018), which grossed approximately $14.1 million worldwide and became the most-watched Mexican film of that year. That same year, he directed
No estoy loca (2018), which reached around 600,000 admissions in Chile and was later ranked fifth in the same Cadem survey. In 2019, he directed
Dulce Familia, which grossed approximately $5.7 million worldwide. His body of work, combining original productions and international remakes, has generated approximately $85 million at the worldwide box office and reached more than 20 million theatrical admissions globally. His films have screened at major international festivals including SXSW, Tokyo, Sundance, Toronto, Sitges and Mar del Plata. == The López case ==
