Matt Damon plays a rising US politician who falls for English ballet dancer Emily Blunt after they meet by chance.

Their relationship is going really well – but strange men in sharp suits and hats seem determined to keep them apart…

Based on a tale by Philip K Dick and pondering destiny and free will, this romantic thriller with a sci-fi twist is more intelligent than most, though the plot struggles to fill two hours.

However, Damon and Blunt really look like they belong together and, with generous helpings of mystery, action and humour, this is slick and satisfying entertainment.
