It is pretty obvious that they were thinking of "Casablanca" by using the name of another north African city as a title for this screwball farce of a spy melodrama involving Nazis. Certainly the plot is ridiculous and totally unbelievable as far as realism is concerned. But so is "Bringing up Baby" that is the definition of screwball. The gags are funny and a delight to watch and listen to,and the cast is first rate in every way. The musical numbers are very good and in general this is entertaining,as movies are supposed to be.
