Also in 2019, it was reported that Williams had been cast in the 1990s-set psychological thriller "The Owners", in which Williams is cast as Mary, a young woman, who reluctantly agrees to participate in a botched robbery with her boyfriend and two other young low level criminals (Ian Kenny, Jake Curran and Andrew Ellis) of an old couple's home Sylvester McCoy and Rita Tushingham. The "Hollywood Reporter" while praising McCoy and Tushingham more, felt that Williams 'used her innate appeal to make her character sympathetic'. "Dread Central" felt that she gave better performance than she did in New Mutants and commented "it’s undeniably cool to see the young, now forever iconic actress kick ass in a real world setting". The film, was released by RLJE Films at select theatres and digital on demand from September 4. The film was directed by French director Julius Berg and adapted from the graphic novel "Une Nuit De Pleine Lune" by Belgian artist Hermann and writer Yves H. Her veteran co-actor Sylvester McCoy predicted success for Williams even beyond her acting progression. "she's full of energy – a little bubbly ball of fire and creativity. The thing is that she’s grown up in the business and she knows it inside out. She knew what she was doing ... she knew what everyone else was doing. She’s a rising star as an actress, but I wouldn't be at all surprised if she became a director and a producer...She's got all those abilities and that intelligence and the knowledge of the business from years of doing it, being steeped in it, from a young age."
