Documentary 'Petro' premieres this week in Bogotá. Filmmaker Sean Mattison followed Gustavo Petro during 2022 campaign.

Mattison: Petro is an enigma; a reserved person and not very adept at being deciphered by friends and strangers. “I feel like I could have gotten more depth if I had more time with him or the chance to accompany him to more places, but I'm still proud of what we achieved,” says Mattison.
