18. Declan Gormley (Jonathan Rhys Meyers)
One of the biggest missed opportunities of the Mission: Impossible franchise is abandoning Ethan Hunt’s most charismatic teammate ever in Declan Gormley (Jonathan Rhys Meyers). In the underrated Mission: Impossible III, he avoided gunfire and the blades of gigantic wind turbines while piloting a rescue helicopter with the same cool he displays while charming angry drivers in a traffic stop he’s created as a diversion with the smoothest Italian you’ll ever hear in this franchise. Was he memorable? Yes. But, since Ethan and his team went on to thwart bigger threats without him, he wasn’t what you’d call an essential part of the franchise.
