★★★★☆ Clueless: The Musical brings a blast of '90s nostalgia to the Trafalgar Theatre in London’s West End. Written by Amy Heckerling and featuring a brand-new original soundtrack by KT Tunstall, this bright and witty adaptation of the iconic 1995 film proves that, even with the West End becoming increasingly saturated with jukebox musicals and movie adaptations, there is always room for more.
