In order for the 90s Queen of Hip Hop Soul to be believable as Justice Charlier, the owner of the Venus Club – and known to break out in rock songs from the 80s [see clip below] – Mary J. said she had to do some heavy research.

“I had to find out – how old is this woman? Who is she? Why is she in the strip club? Does she trust men anymore? Does she hate men? Is she gay? What is she?” said Mary J. during interviews for the film in Los Angeles on Sunday. “I definitely had to go look at some different women and talk to different women and even do some method acting, like going to strip clubs myself, just to feel that out.”
