Which actor played Jack Harmon in the first Mission: Impossible film?

Emilio Estevez played Jack Harmon in the first Mission: Impossible film.

Jack Harmon is part of the IMF team assigned to a mission in Prague at the beginning of the 1996 movie. Estevez’s role is brief but important because the mission’s disastrous outcome drives Ethan Hunt’s investigation into a possible mole within the IMF.

The cast also included Jon Voight as Jim Phelps, Emmanuelle Béart as Claire Phelps, Jean Reno as Franz Krieger, and Ving Rhames as Luther Stickell. Because Estevez appears only in the opening operation, viewers sometimes overlook his character when listing the film’s principal team members. The Prague mission establishes the movie’s central mystery before Ethan begins working outside official IMF support.
