Charlotte Rampling plays the lead opposite Gabriel Byrne in her son Barnaby Southcombe’s directorial debut. Southcombe’s screenplay is based on the novel I, ANNA by Elsa Lewin. The film is reminiscent of seventies and eighties film noir where ambiguous and obsessive relationships take precedence over procedural drama.
