This action-thriller stars Bruce Willis, Radha Mitchell, and Rosamund Pike in an alternate world where people live their lives from inside the safety of their homes through the use of highly sophisticated androids. These surrogates, after which the film is named, allow people to assume practically any identity they choose. Everyone has perfect skin, a ridiculous body, and super-human strength and speed, although the ability to run fast or jump high is only used when necessary. A couple of well-timed plot twists were enough to keep me surprised, while the relatively quick pace of the storyline and believable special effects had my interest. Most importantly of all, this film makes you think - about identity, about how technology shapes our relationships with other human beings, and about the dangers of using machines as a buffer for real, old-fashioned interpersonal communication. This was well worth the watch.
