Oh! Those Most Secret Agents (1964)

Franco and Ciccio - yes the same comic team who were in the Eurospy parodies Dr. Goldfoot and the Girl Bombs, The Amazing Dr.

I suppose since no one else has commented on "002: Agenti Segretissimi" on IMDb I should write a brief plot summary for it, but this movie barely has a plot: American, Russian and Chinese secret agents are chasing Franco and Ciccio around the French Riviera because they are in possession, unbeknownst to them, of a valuable formula (in other words, a McGuffin). It's really just a series of loosely connected vignettes and skits - and director Lucio Fulci, still young and inexperienced, lingers too long on each one of them.
