¨Sister what have you done ?¨ is a so-so but entertaining Spanish comedy about nuns with likable and appealing characterizations by all Spanish-star-cast . Pedro Maso comedy with the sympathetic actress Lina Morgan and a great plethora of Spanish actors . Mediocre but fun comedy dealing with rogue people , swindlers , and heists . It stars Sor Ángela (Lina Morgan) and Sor María (Tote García Ortega) who pull off a bank holdup along with a gang of small-time delinquents (Beatriz Rico , Neus Asensi) . The nuns want the cash to get better their convent in the Monasterio de Lupiana, Guadalajara run by a stiff Superior Mother . But it results to be an utter flop because of the moment the nuns execute the crime , they are double-crossed and the loot is taken by the other thieves . Furthermore , Sor Angela has a twin sister called Trini Montero , a famous Revista Farceur , she is then accused for heist and things go awry . Meanwhile , the religious women are pursued by two Police Inspectors (Luís Fernando Alvés and Jesús Castejón) , but the intelligent nuns demonstrate their escapist skills and taking place bungling operations , confusion and mayhem . Funny and uneven comedy , appointed for all kind of public about a silly premise : a botcher duo of nuns : Morgan and Ortega , carry out tiny robbing to finance their poor convent , while being chased by Police . It takes a simple concept , a band formed by two nuns and other shameless delinquents execute a bank robbing , but happenings get awry . The picture deals with hold-up , thefts and tricks in similar style to classical films of Commedia all'Italiana of the fifties and Spanish comedies if the sixties . It follows the wake of known films as ¨Los Tramposos¨, ¨Atraco a Las Tres¨, and "They Who Play the Piano" . This flick is a comical and sometimes disconcerting account of two nuns from an economic perspective , because needing all of them , urgently , amount of money to resolve the problematic existence of a convent about to an eviction . Here there are great amusement , some nice jokes , comical sketches and the cast plays eccentric characters . It is a nutty Spanish comedy that offers no intellectual stimulus whatsoever , though it has some attractive and hilarious moments . The film attempts to give laughs but it falls short , resulting in a mediocre and sometimes embarrassing film . Bemusing story with enjoyable but also absurd moments and charming acting by a likable comedian : Lina Morgan , showing some Revista numbers in her successful theatre La Latina , Madrid . An enticing but disconcerting Spanish comedy film and with its ups and downs ; here our protagonist , the great Lina Morgan , provides her real comical entertainment .
