Sean Penn Sean Penn

Sean Penn reportedly played a key role in last week's arrest of Mexican drug lord Joaquin "El Chapo" Guzman.

In late 2015, the actor secretly interviewed El Chapo, who was recaptured Friday after escaping from a maximum security prison for the second time in July. Portions of their interview, which was conducted at a secret hideout in Mexico, were published on Rolling Stone's website on Saturday.

El Chapo wanted to meet with Penn and other Hollywood actors and producers to discuss a possible biopic about him. In an article for Rolling Stone, Penn details the seven-hour meeting that was facilitated by Mexican actress Kate del Castillo, whom El Chapo wanted to be involved in the film.

"The trust that El Chapo had extended to us was not to be f---ed with," Penn writes in the Rolling Stone article. "This will be the first interview El Chapo had ever granted outside an interrogation room, leaving me no precedent by which to measure the hazards. ... I took some comfort in a unique aspect of El Chapo's reputation among the heads of drug cartels in Mexico: that, unlike many of his counterparts who engage in gratuitous kidnapping and murder, El Chapo is a businessman first, and only resorts to violence when he deems it advantageous to himself or his business interests."

After their meeting, Penn says El Chapo sent him and Castillo a videotaped recording in which he answered several questions provided by Penn.

Asked about his business, El Chapo responded: "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."

The Associated Press quotes a Mexican federal law enforcement official as saying it was El Chapo's chat with Penn that made authorities aware of his whereabouts.

El Chapo is expected to be extradited to the United States to face drug trafficking charges.
