The Hypnotist, based on yet another bestselling Swedish crime novel, will start principal photography this coming winter for release in fall 2012; pseudonymous writer Lars Kepler (actually the duo Alexandra and Alexander Ahndoril) plan to continue a series featuring Detective Inspector Joona Linna.
The story starts with the murder of a man in a Stockholm suburb, followed by the killing of his wife and a daughter at their home. One injured son survives; when Linna realizes there is another daughter the clock starts ticking. When she persuades a reluctant doctor to hypnotize the son, things swiftly spiral out of control.
The Hypnotist is produced by AB Svensk Filmindustri and Sonet Film AB, producers Börje Hansson, Peter Possne and Bertil Ohlsson. Hallström and the producers will attend the Berlin International Film Festival, where the film is being sold internationally. Hallström recently directed the UK's Salmon Fishing in the Yemen, which is in post-production, starring Ewan McGregor, Emily Blunt and Kristin Scott Thomas. It is set for December release overseas; it seeks a U.S. distributor.
