This was the second Pink Panther feature, and the one that set up all the elements that would become familiar: disaster-causing Inspector Clouseau, his wrathful chief Dreyfus, his attack-ready manservant Cato. Clouseau was just a scene-stealing supporting role in The Pink Panther. Here he's in the limelight. Sellers, naturally, is a riot, and Clouseau's blinding crush on Maria provides a stronger motivation for the detective's refusal to indict the maid than just sheer arrogance and stupidity.
Nobody watches Inspector Clouseau movies for the plots, although this one is a bit more story-driven and actor-centered than most of them, and its slapstick had not yet reached the epic-scale stunt proportions of the later movies. In fact, A SHOT IN THE DARK is based on stage play about a foolish judge, which was retro-fitted as a vehicle for the bungling detective character. It's not at all stagey, and the cast is a great display of star power. This may be the most exposure young kids get to British actor George Sanders, here playing Maria's aristocratic employer Ballon. A specialist in playing suave English cads and blackmailers, Sanders' distinctive voice and mannerisms were copied in countless cartoons for decades.
