'Shrek: The Musical' Somebody once told me — that Weston Theater’s Young Company debuts its production of Shrek: The Musical this week. Based on the beloved 2001 film (itself based on a picture book by William Steig), it’s a tale as old as time: A reclusive ogre gets roped into a rescue mission by a slimy lord, saves the princess, finds more than he bargained for and learns a lot about self-love along the way. With a cast including Eli Hamilton as Shrek, Tomias Robinson as Donkey and Emma Diner as Fiona, the show premieres at Walker Farm before taking off on a tour around southern Vermont.
