It was earlier reported that Hardwicke was eyeing Thirteen actress Evan Rachel Wood to star in the erotic thriller, but scheduling difficulties got in the way of Wood signing on.
The movie, co-written by Hardwicke and Thirteen scribe Artie Nelson, tells the story of a psychic psychologist who sees the memories of his patients to help them let go of the past. He crosses paths with the Browning character, who also has the same power.
Browning is best known for roles in A Series of Unfortunate Events, Sucker Punch and Sleeping Beauty.
She was recently up for the title role in the Carrie remake, but lost out to Chloe Moretz.
Plush is due to start filming this fall.
