Benji Dunn (Simon Pegg)
Ever since his introduction in Mission: Impossible III, Simon Pegg has served as a core member of Ethan Hunt’s IMF ensemble and the most consistent source of comedic relief throughout the new installments. In the role of Benji Dunn, a former off-field agent who became a technical field agent in later installments in the series, Pegg has proven himself to be a warm, vibrant presence, one that is always quick for a reaction shot whenever Ethan Hunt is putting his life on the line, but also there to provide key assistance and motivation when needed. Even during the inconsistent early installments in the franchise, Pegg’s presence provided a comfort. Seen celebrating with the team after another successful mission in Fallout, we should expect Benji to be there for Ethan Hunt once more for this penultimate addition to the constantly-growing action franchise, as well as (hopefully) the next movie as well.
