Su Excelencia (aka Your Excellency) is a 1967 Mexican political satire film directed by Miguel M. Delgado and starring Cantinflas and Sonia Infante.

In Cantinflas and the Chaos of Mexican Modernity, Professor Jeffrey M. Pilcher argued that despite how Cantinflas's character "refused in the end to cast his vote for either side and spent a full fifteen minutes haranguing the rival powers in the name of world peace; nevertheless, he lost the moral high ground of nonaligment through his blatant anticomunism", in reference to the film's storyline about the machinations of Pepeslavia (a clear Soviet Union analogue) to get the character's vote.

[3] In his Concise Encyclopedia of Mexico, Michael Werner listed the film among those in Cantinflas's later filmography (from El analfabeto onwards) that were "preachy, tedious, and humorless", saying that in the final speech he "offers the Christian doctrine as a solution for the world's problems in an international scenario meant to represent the United Nations".

[4] In Looking for Mexico: Modern Visual Culture and National Identity, John Mraz was more critical; sharing similar conclusions to Werner's, but also adding that the final speech showed that "[Cantinflas's] arrogance was unbounded", and that he was "taking himself very seriously".
