New York Times:
Top Secret! comes nowhere near Airplane! but in its own cheerful, low-pressure way, it's about as amiable an entertainment as you will find this summer.
The plot combines the rock musical with the spy thriller (not to mention assorted other genres), and the comic invention is fairly constant.
This movie will cheerfully go for a laugh wherever one is even remotely likely to be found.
This time, though, the creative group has neglected to build to the kind of giddy, everything-plus-the-kitchen-sink climax that made Airplane! such a memorable exercise in anarchy.
Signs of desperation have begun to creep in some time before the end.
Secret! shares the same wonderful wacky attitude that allows just about any kind of gag to come flowing in and out of the picture at the strangest times.
