Chloe (2010)

Gynecologist Catherine Stewart (Julianne Moore) suspects her professor husband (Liam Neeson) of having an affair (or affairs) with his female students, so she hires a pretty young girl, Chloe (Amanda Seyfried), to seduce her husband and prove her suspicions. Chloe meets with Catherine to give her reports, and subtly tries to seduce the older woman and eventually succeeds. When Catherine subsequently rejects her, Chloe has sex with Catherine's teenage son Michael (Max Thieriot), as a way of "getting closer" to Catherine. Things grow dangerously out of hand as Chloe becomes more and more obsessed and unhinged.

The four characters behave and relate to one another in emotionally realistic ways, and the fatal lack of communication that leads to their troubles seems painfully genuine. Where the movie goes slightly wrong is in the thriller portion, wherein the Chloe character behaves more and more irrationally, out of love and/or obsession for Catherine. Her obsession turns homicidal, and the final act of the movie becomes an almost standard-issue Hollywood erotic thriller. Not to mention the odd coincidences that bring all these characters together. But overall, the strong characters and Egoyan's patient, thoughtful mood and pacing make it an above average effort.
