Jesse Loughborough’s review published on Letterboxd :
I understand this was originally made as a David Niven vehicle. Now, I like Niven as much as the next man (after all, he is responsible for the single best moment in Oscars history) but the scenes with him are generally as dull as dishwater. And the less said about Robert Wagner, the better. It was perhaps just a happy accident that the Clouseau character was a stroke of genius because Sellers, with a little help from Capucine, completely saves the day.
