“Petro.” Watch the documentary by Sean Mattison and Trevor Martin following Gustavo Petro during his run for the presidency of Colombia in 2022. "Petro" begins in September 2021 at the launch event of Gustavo Petro's campaign. The documentary makers enjoy unprecedented access to Colombia's most charismatic and polarizing politician, the film follows the highs and lows of the Colombian progressive movement and Petro's historic campaign for president through Election Day. On the Colombia Calling podcast this week, we speak to Sean Mattison about the documentary, how it came to be, what Petro is like behind the scenes and with his family, why the president is so polarizing and accusations of propaganda.
