The play has been translated into all European languages and remains popular, inasmuch as it deals with the hypocrisies of everyday life along with the corruption perpetrated by the rich and privileged. In the Netherlands, for instance, André van Duin made his own Dutch version of the play called De Boezemvriend (meaning "bosom friend", "best buddy"); the 1982-filmed movie is set in the Netherlands during the Napoleonic era with Van Duin playing tooth-extractor Pasdupain aka Fred van der Zee (which actually translates as "Breadless" rather than "Painless").
In Marathi, P. L. Deshpande adapted this play as Ammaldar (literally "the Government Inspector") in the late 1950s, skillfully cladding it with all indigenous politico-cultural robe of Maharashtra, while maintaining the comic satire of the original.
