jlage’s review published on Letterboxd:
It has enough goofy charm to rescue it from its ridiculousness, though de Broca hoists himself on his own petard seeking set pieces (the wharf brawl, the jungle rescue) that attempt to dazzle and thrill at the expense of some semblance of plausibility that would allow for that. Spielberg would refine these thrill sequences skillfully in the Indiana Jones movies partly inspired by Man from Rio. Still, as a study for what would come 17 years later, Rio ain’t too bad. Big question is how Belmondo managed to survive all the abuse he was called upon to endure.
