Identity is the kind of thriller we haven't seen in a while from Hollywood, the Ten Little Indians scenario where a large group of people are being killed off by an unknown adversary and the suspense level rises until a significant plot twist turns the whole thing on its ear. That's a good movie and Identity, which the exception of some minor hiccups, lives up to it.
A good ensemble cast, including John Cusack, Ray Liotta, Rebecca DeMornay, Amanda Peet, and John C. McGinley, provide adequate amounts of star power and tension. Director James Mangold has proven he can handle this type of material and cast as the director of Copland. In this film he takes a limited location, sets his characters up well, and more or less lets things unfold as they will without forcing the issue.
The one problem is this - if you remember the commercials for the film that ran on television when it opened, they revealed a very important plot device that doesn't give away the big revelation, but comes damn close. In addition, if you are really paying attention, it's not all that hard to guess what it is. This isn't to say that it takes anything away from the film at all. It's very clever and certainly holds your interest for the duration. An argument could also be made that the ending feels tacked on, but at 90 minutes, there's no wasted scenes or extemperaneous dialogue. The DVD does come with an extended version, as well as commentary from Mangold.
An excellent popcorn thriller.
