Liam Bates has launched Oyster Lane Theatre Group’s (OLTG) new show, The Producers, which plays at The National Opera House from Tuesday, November 28 to Friday, December 1. The Producers is based on the 1968 film by Mel Brooks and is described as “a laugh-out-loud, outrageous, crowd-pleasing farce” which has sold out theatres worldwide since its 2001 debut.
