Steve Pemberton and Reece Shearsmith’s Inside No. 9: Stage/Fright at Wyndham’s Theatre is a darkly comedic treat that brings their beloved anthology series to the stage. The show masterfully blends humor and horror, featuring nods to classic episodes like “Bernie Clifton’s Dressing Room” and introducing new material that keeps audiences on their toes. Their sharp wit shines through, especially in their playful jabs at West End conventions and celebrity culture. While the structure leans heavily on familiar sketches, the production’s self-awareness and theatrical flair make it a must-see for die-hard fans. With its clever twists and atmospheric staging, Stage/Fright offers a unique and entertaining night out.
