Mel Brooks’ The Producers was a legendarily successful translation from film to stage, but Young Frankenstein, his classic 1974 horror spoof film of Mary Shelley’s gothic tale, proved more problematic on Broadway in 2007. The sprightly 91-year-old Brooks personally oversaw this London revival, along with original director and choreographer Susan Stroman. This lower-budget production in a more intimate space makes the most of a relatively simple set of backdrops by designer Beowulf Boritt, showcasing Brooks’ inventive lyrics and music. The question is, can music hall innuendo survive not just political correctness, but more problematically, the recent outing of sexual exploitation? Laughing out loud through the dazzling – often smutty – lyrics Brooks wrote in his 80s (”Though your genitalia have been known to fail ya”) for me the answer is a giggling yes. And judging from audience laughter from both sexes, I’m not alone.
