Tom Cruise is back as IMF Agent Ethan Hunt, who is framed for the bombing of the Kremlin by a twisted mastermind out to start World War III. Disavowed by the US government, Cruise and his merry band of super agents - including newcomers Paula Patton and Jeremy Renner and franchise mainstay Simon Pegg - have to fight to survive and stop nuclear armageddon. Splashy, stylish and lots of fun, 'Ghost Protocol' is the most highly rated installment in the franchise. Worth a watch if you've never seen it.
