When the theatre play Jeffrey Bernard Is Unwell by the British author Keith Waterhouse opened in Prague in March 2009, it became an instant success. The tragicomic show starred a leading Czech actor, Oldřich Kaiser, in the part of the heavy-drinking London journalist Jeffrey Bernard. But the play was cancelled in November because Mr Kaiser, just like the main character, was himself struggling to deal with alcohol abuse. Earlier this month, however, Mr Kaiser returned on stage as Jeffrey Bernard at another venue in the capital.
