Gillian Anderson and Rebecca Hall are set to face off in The Portrait, a new psychological thriller from writer-director Sara Colangelo that turns an illicit affair into a dangerous game of deception.
The film, adapted from Ilaria Bernardini's novel, brings together two acclaimed actresses in a story exploring obsession, betrayal and the complicated power dynamics between two women connected by the same man.
A Wife, a Mistress and a Dangerous Secret
Anderson will portray Valeria, an internationally acclaimed writer who has spent years maintaining a secret relationship with Martín, a wealthy businessman.
When Martín becomes seriously ill and Valeria can no longer reach him, she devises an unusual plan to remain close to him. She commissions his wife, Isla, played by Hall, to paint her portrait.
The arrangement gives Valeria access to the couple's London townhouse, where the boundaries between wife and mistress begin to collapse.
What follows is a psychological confrontation in which neither woman fully understands the other's intentions.
Sara Colangelo Takes on a Story of Female Power
Colangelo, whose previous films include The Kindergarten Teacher and Worth, will write and direct the adaptation.
The filmmaker has expressed an interest in exploring moral ambiguity, female transgression and the ways women exercise power.
Anderson, known for The X-Files, The Crown and Sex Education, joins Hall, whose credits include Passing, The Night House and The Beauty.
The pairing places two performers known for portraying emotionally complicated characters at the center of a thriller driven by secrecy rather than spectacle.
When Will 'The Portrait' Be Released?
Production is scheduled to begin in the United Kingdom during the first quarter of 2027.
The project is being introduced to buyers ahead of the American Film Market, with WME Independent handling domestic sales and Rocket Science overseeing international sales.
Talia Kleinhendler and Osnat Handelsman-Keren of Pie Films are producing alongside Francesca Cualbu of The Apartment.
A distributor and theatrical release date have not been announced.
For audiences drawn to sophisticated psychological thrillers, The Portrait offers a premise built around two women whose relationship begins with a lie—and whose confrontation could expose far more than an affair.
