S.J. Watson's debut novel "Before I Go to Sleep" follows a woman suffering from anterograde amnesia: each day, she wakes up with no idea of who she is and must put together the pieces from a journal she has been keeping.
In "Memento," Christopher Nolan's remarkably artful amnesia film, Guy Pearce used Post-it notes, Polaroids and tattoos on his own body to solve a murder. In "Before I Go to Sleep," Christine, the protagonist, tries to find the truth behind the attempt on her own life that caused her amnesia, while being guided (or perhaps manipulated) along the way by her husband and doctor.
Rowan Joffe ("Brighton Rock") directed the film adaptation of Watson's novel, due out September 12 in the U.S. The film stars Nicole Kidman, Colin Firth and Mark Strong and is produced by Ridley Scott.
