Brett Ratner is producing the action-comedy, which also stars Samuel L. Jackson, Jessica Alba and Sophie Turner
Kyle Newman (“Fanboys”) is directing the action-comedy from a script by John D'Arco.
RKO Pictures and Hopscotch Pictures are producing with Ratner's Rat Entertainment, whose John Cheng will executive produce.
Jessica Alba and Sophie Turner (“Game of Thrones”) co-star in the film, which finds Steinfeld playing a 16-year-old assassin who fakes her own death in pursuit of a “normal” adolescence.
Basso will play Steinfeld's wild best friend.
Basso, who was one of the young stars of J.J. Abrams’ “Super 8,” is perhaps best known for playing Laura Linney‘s son on Showtime's “The Big C.” He was last seen alongside Nick Robinson and Moises Arias in Jordan Vogt-Roberts charming coming-of-age comedy “The Kings of Summer.”
Basso is represented by ICM Partners, Industry Entertainment and attorney Howard Fishman.
