Ethan Hunt is an IMF agent and the main protagonist of the Mission Impossible franchise. Tom Cruise recently portrayed the character, reportedly for the last time, in Mission Impossible: The Final Reckoning. Here's the official synopsis:

At the end of Mission: Impossible – The Final Reckoning, Cruise manages to wrestle the AI key from Gabriel while the pair fight in the cockpit of a biplane. Gabriel falls from the plane, hitting his head on the tail and plummeting to the Earth (the fall will have killed him, but we don't actually see him die).

The Final Reckoning" leaves the door open for future movies. Is this really Tom Cruise's last "M:I" movie?
