Jennifer Lopezdid a little field research while filming her upcoming movieHustlers.

In a new interview withVulture, the movie’s writer and directorLorene Scafariareveals how Lopez and husband-to-beAlex Rodriguezhelped make the movie about strippers as authentic as possible.

“She and Alex went and visited a strip club, and she was able to give me some … insights,” Scafaria told the outlet.

The movie is based on the2015New Yorkmagazine article on a group of New York stripperswho scammed men out of hundreds of thousands of dollars. And it all clicked into place once Scafaria got Lopez, 50, on board.

“The moment I finished the script, I realized, ‘Oh my God, Ramona isJennifer Lopez,’ ” she said. “’Jennifer Lopezis Ramona. The two of them are the same; they have all of these similar qualities. It has to be her.’Casting was made infinitely easier once Jennifer was attached. Everybody really, really, really wanted to work with Jennifer. That was the beauty of making this movie, too: casting what felt like the right people for each part, and watching them interact the way that they should with each other.”

“She’s obviously such an unbelievable dancer, but she trained so hard-core for this,” Scafaria said about Lopez. “Pole dancing is not like anything else. It required muscles you don’t know you have. So we did treat it a little bit like a sports movie in that way.”

In addition to the two Grammy nominees, the cast also features several other notable stars:Crazy Rich Asians’Constance Wu,Riverdale‘sLili Reinhartas well asKeke PalmerandJulia Stiles.

In aninterview withDeadline, Scafaria expressed her excitement towards the film, saying, “I’m thrilled to have the opportunity to work with this dynamic group of women. We’re grateful to have assembled such a powerhouse cast and can’t wait to start filming at the end of the week.”

Hustlersopens Sept. 13.
