From start to finish, The Invasion is a complete mess. It was supposed to be a modern retelling of Invasion of the Body Snatchers, but it was so poorly written and marketed that this didn't hit home with the public. Worst of all, the movie was a complete waste of two talented actors: Nicole Kidman and Daniel Craig. But it’s Kidman that stands out; her performance is single, dull note resounding for the film's 99 minutes.
Not given much to work with, Kidman sleepwalks through the movie. That this is the perfect complement to the actual energy of the film is telling. The whole project was such a misguided affair that it was partially re-shot by a different director after the studio grew nervous about the film. They had good reason.
