Those mocking the premise of this movie would also be mocking the premise of a movie about a department store Santa Claus who thinks he's actually is Santa Claus. If the script had been punched up a bit and the direction and editing had been given a better rhythm, this could have been on par with "Miracle on 34th Street". As it is, it is still enjoyable and came as a bit of a surprise for me since I thought I had seen nearly all Cary Grant movies. there is one major plot hole though. You think they would have provided such a valuable caterpillar more protection.
