As impressive as the bike jump off a cliff is, that’s only the appetiser in a particularly audacious action finale. In the particularly relevant, perhaps penultimate Mission: Impossible, Ethan Hunt (Tom Cruise) and his IMF team battle an AI that has gained self-awareness and is sewing chaos and the threat of nuclear war across the world. DEAD RECKONING PART ONE is touching on three hours but somehow doesn’t feel like it. Famously, since Christopher McQuarrie took over the reigns of the franchise, ideas for action scenes are thought up first and the script weaved between them, so the final product is miraculously coherent considering. The scale and stakes have never been higher and Cruise and the cast, particularly new addition Hayley Atwell, couldn’t be more game for whatever madness is thrown at them. What on earth will they come up with for Part Two? SSP
