The trio will appear alongside the already announced Jennifer Lopez, who will play the titular character in the Netflix thriller.

Newcomer Paez is set to play the daughter of Lopez's character, an assassin who comes out of hiding in order to protect her girl, who she gave up years before.

Fiennes and Bernal are set to portray dangerous characters in the film, while Hardwick will play an FBI agent who is on Lopez's side.

Niki Caro will direct the movie, and Misha Green is in charge of the script, with edits from Andrea Berloff.

Lopez is also co-producing the film for the streaming giant.

Benny Medina and Molly Allen are to executive produce the movie.

The 52-year-old star - who previously played Detective Harlee Santos in the TV series 'Shades of Blue' - will portray FBI agent Nina Guerrera in the movie based on Isabella Malondo's best-selling novel.
