The real-life story of Robert Mazur and his time undercover with the cartels is adapted into film in The Infiltrator, but some creative liberties are taken with the material. Bryan Cranston leads The Infiltrator’s cast, playing Robert Mazur, who participates in the money laundering schemes of infamous criminals like Pablo Escobar, gathering information under the name Bob Musella. By helping criminals like Roberto Alcaino (Benjamin Bratt) launder their money, he earned enough trust and credibility with the cartels to help law enforcement take down the corrupt Bank of Credit and Commerce International, as well as making over 100 arrests.
