This film really does make the equivalent Carry On movies extremely juvenile. Very rarely, if at all does this film delve into lavatorial/innuendo humour. All of its humour is based on slapstick and a terrific script full of one-liners that you never tire of viewing. They could have made a sequel, but then the humour would have soured in the same way that the Naked Gun or Airplane films did. All the characterisations are spot on, everyone except Striesand is portrayed as being bumbling unsubtle fools including the CIA and Russian spys. It's basically a change to see the Americans not taking themselves seriously for once. Kenneth Mars is very amusing as O'Neal's opponent for the music grant. Of particular note is the car chase in San Francisco in an exaggerated Bullitt style. Granted, it is very dated - it's 1972 and chequered flares and velvet is much in evidence, but this adds to the film's charm. It is one of the few films that I was sad to see ending...
