Before I Go to Sleep (2014) is a tense psychological thriller that masterfully explores themes of memory, trust, and identity. Directed by Rowan Joffe, the film stars Nicole Kidman as Christine Lucas, a woman who wakes up every day with no memory due to a traumatic accident. She relies on her husband Ben (Colin Firth) and a doctor (Mark Strong) to piece together her past, but as she begins to keep a secret journal, terrifying truths emerge that challenge everything she believes.

Nicole Kidman delivers a compelling performance, capturing Christine's vulnerability and growing paranoia with nuance. Colin Firth is equally effective as the seemingly caring husband, whose motives become increasingly ambiguous. The film's direction maintains a claustrophobic atmosphere, using tight shots and a muted color palette to heighten the sense of unease. While the plot twists may feel familiar to thriller enthusiasts, the execution is solid, keeping viewers engaged through its 92-minute runtime.
