Enemy (2013)

A man seeks out his exact look-alike after spotting him in a movie. (IMDb)
A goosebump-inducing premise here is expertly developed, thanks to a deliciously detailed and well thought out screenplay and a strong performance from Gyllenhaal. A constant sense of discomfort pervades the entire film as even the simplest conversations or sequences are given uneasy undertones. The feeling grows as the plot gets continually weirder, darker, and more confusing. It’s one of those complex films you need to Google to understand completely, but it’s no less thrilling in the moment.
8/10 (Great)
