This intriguing sci-fi thriller poses some big questions regarding the future for communications technology and what, indeed, it means to be human. In a world where much of the population has robotic alter egos to take care of their day-to-day work, a dogged police detective discovers a potentially lethal glitch in the connection between humans and their "surrogates". Since Bruce Willis does no-nonsense, world-weary lawmen to a tee, his very presence signals that all is not well in this brave new world of "surries" - whose chiselled, bodacious forms represent the users' idealised versions of themselves (Willis's model even has a thick head of hair!). A murder case where the destruction of a party-going surrogate also effects a splattery demise for its human master sets in motion what becomes an increasingly plodding conspiracy plot. The requisite car chases and fisticuffs are present and correct, yet it's the underlying story of Willis's failing relationship with wife Rosamund Pike (who's excellent) that adds a resonant emotional layer not often found in popcorn action flicks.

Set in a futuristic world where humans live in isolation and interact through surrogate robots, a cop is forced to leave his home for the first time in years in order to investigate the murders of others' surrogates.
