I needn't have worried: Ethan Hunt lives to fight another day in Mission: Impossible – The Final Reckoning. He defeats Gabriel in a mid-air dogfight, and puts the poison pill in the Entity's podkova, allowing it to be trapped in Luther's ingenious 5D data drive.

The actor behind Benji Dunn sums up two decades' worth of challenges making these movies: "Every 'Mission: Impossible' I've ever done has had a parallel 'Mission: Impossible' running alongside it, which is making 'Mission: Impossible.

The Mission: Impossible series has never been one for subtlety, but The Final Reckoning takes the cake as the most grandiose and self-indulgent movie of the lot. Its story is muddled and melodramatic, yet when the plot makes way for stunts and spectacle, the sheer dedication of Tom Cruise and co. is hard to resist.

Don't worry, it's not an off-screen character that was suddenly introduced. Phineas Phreak is the hacking code name for Luther and is first mentioned during 1996's Mission: Impossible while Ethan is hunting for fellow disavowed IMF agents to break into the CIA Black Vault in Langley.
