Is Sean Penn in trouble after interviewing the notorious Mexican drug Lord Joaquin “El Chapo” Guzman? Sean Penn had met with the fugitive drug lord in the Mexican jungle in a secret meeting.

Hollywood Reporter is unsure whether Penn will be required to testify against El Chapo; or if he will be subpoenaed; or if he will have to cooperate with the U.S. Attorney’s office in Chicago, which is leading the American end of the case. The Mexican authorities want to talk to Penn too.

The interview was conducted in October after Guzman’s jailbreak and is published by The Rolling Stone magazine. Guzman has been arrested again and returned to the maximum-security Altiplano jail, from where he escaped in the first place.

If you are thinking how Penn ended up meeting El Chapo? Here is how. According to the information on Sydney Morning Herald, in 2012, Mexican actress Kate del Castillo had posted a Twitter message that was sympathetic to Guzman. One thing led to another and a dialogue started between her and Guzman’s lawyers and then with Guzman himself.

Guzman who was behind the bars then asked for her help to make a biopic on him. It is believed that Sean Penn met the actress after Guzman’s jailbreak through mutual friends, who were involved in the project. These friends, on Sean Penn’s recommendation, opted for a story instead of a movie.

The 7-hour and 11000-word long interview has Guzman talking about his beginnings and his drug trade. At one point he is quoted saying, “I supply more heroin, methamphetamine, cocaine and marijuana than anybody else in the world. I have a fleet of submarines, airplanes, trucks and boats.”

“Well, it’s a reality that drugs destroy. Unfortunately, as I said, where I grew up there was no other way, and there still isn’t a way, to survive; no way to work in our economy to be able to make a living,” he replied when asked about the drug trade.”
