The title says that one does not shoot at angels; hum, maybe, but do not tempt me as this is a humourless and overstrained crime-comedy with Ruth Leuwerik as a nun in a combination of Chesterton's Father Brown and Agatha Christie's Miss Marple. Leuwerik is totally incapable for the job and plays the part as if she is on the verge of a nervous breakdown. Gustav Knuth and Boy Gobert try hard to make something of their characters and sometimes succeed, but they fight a losing battle with the weak material. Rolf Thiele was very talented director, but he did not know the first thing about comedy; and probably he was another victim if the declining German/Austrian cinema in the 60's as well.
