Due to the fact that Director Mircea Dragan was not used to direct comedies he gave few indications to the cast and allowed the actors in this comedy to improvise.
Actress Ioana Dragan who played the role of Lieutenant Paula Deleanu was the actual wife of Director Mircea Dragan.
The German Shepperd dog Costel was a real police dog and his real name was Rurich.After many hours of filming the dog was tired and was barking continuously, annoying the cast.Actor Sebastian Papaiani kept him quiet by feeding the dog bags of pork liver.
