Not as bad as the average German farce of the last 30 years, but still an indifferent, seldom really funny film, that is a kind of poor man's version of Kind Hearts and Coronets (with Alec Guinness). It is painful to see how bad most jokes are timed. The end sequence (labyrinth of mirrors) seems to be borrowed from Orson Welles' Lady from Shanghai; and as this is not used for e.g. a subtle parody, there is no excuse.
