A biographical film about Jair Bolsonaro, Brazil’s former president who is currently imprisoned, is underway, as confirmed by his son, Carlos Bolsonaro.

Carlos shared the news on the social media platform X, coinciding with his brother Flavio’s announcement of his candidacy for Brazil’s 2026 presidential election. In the post, Carlos expressed admiration for American actor Jim Caviezel, who is set to portray his father in the upcoming film.

“Jim Caviezel, thank you for everything,” Carlos wrote, praising the “Passion of the Christ” star as a person whose legacy will be “admired by good people and envied by those who seek destruction.”

He went on to say that collaborating with Caviezel had provided him with “one of the greatest gifts” of his life, concluding the message with the words, “God, Jesus, and Freedom.”

Caviezel has previously been associated with far-right conspiracy movements in the United States and has faced criticism for the political undertones in some of his acting roles.

He also famously starred as Jesus in Mel Gibson’s “The Passion of the Christ” and “The Sound of Freedom.”

According to The Guardian, the biopic, “Dark Horse,” presents a heroic vision of Jair Bolsonaro and is based on Bolsonaro’s successful 2018 campaign for the presidency.

Jair Bolsonaro remains in prison after receiving a 27-year sentence for attempting to overturn the 2022 election results.

Authorities said he orchestrated a plot to invalidate President Luiz Inácio Lula da Silva’s victory, leading to his imprisonment in September.

In addition to his sentence, a separate ruling has barred him from holding office until 2030, effectively ending his political career.

From prison, the former president issued a rare public endorsement naming Flávio as his preferred successor.

According to The Associated Press, Flávio, 44, has confirmed through his Senate office that he will run in the October 2026 presidential election against the candidate of the Liberal Party.

Flávio, who is the eldest of the brothers, described his decision to run as “irreversible,” setting up a direct challenge to President Lula, who is seeking a fourth nonconsecutive term.

“It is with great responsibility that I confirm the decision of Brazil’s greatest political and moral leader, Jair Messias Bolsonaro, to entrust me with the mission of continuing our national project,” Flávio wrote on X.

His office also confirmed he has visited his father in prison.

Production on “Dark Horse” is expected to continue into 2026, with filming planned in both Brazil and Mexico.
