Parents need to know that Clouseau addresses his Asian manservant Cato in racially-condescending terms ("my little yellow friend"), and that the movie's ostensible "good guy" (apart from Clouseau) is a charming career thief who's not above intimidating a weasel supporting character via torture. There is gunplay for comic effect.
Positive messages:Mixed, since Inspector Clouseau, while wholly on the side of righteousness and justice, is an arrogant clown, while the bright and good-looking Sir Charles is a professional thief (and his pretty wife is no better).
Violence:Some slapstick fights. Chief Inspector Dreyfus tries to shoot/strangle Clouseau (harming himself and others instead). Some mildly 007-type action as Sir Charles tangles with armed thugs. Running joke about him bullying one of their flunkies by breaking the man's fingers.
Sex:None, unless you count Clouseau, attempting to trap Sir Charles, dressing up as a lounge lizard (with half his mustache missing) and trying to seduce the jewel thief's wife.
