Perhaps it’s no surprise that the dominant colour in a movie musical about a community’s reaction to a British serial killer of prostitutes should be grey. Alecky Blythe’s revolutionary stage production (music by Adam Cork) gets a screen adaptation by director Rufus Norris. We hear the real-life transcripts of interviews with local residents in Ipswich related in halting, lilting, compositional style with appropriate pauses and inflexions as truck driver Steven Wright is arrested in their midst. Ten weeks! they cry. He only lived here ten weeks! This small part of town has seen an upswing in sex workers and it’s lowered the tone somewhat. In a mostly anonymous cast who sing through and use Sprechgesang technique Olivia Colman has the biggest role as a woman trying to get things back on an even keel, encouraging people to create hanging baskets leading up to a garden competition that concludes the reparations. Tom Hardy is the serial killer expert driving a taxi. One outstanding song is It Could Be Him performed by two teenage girls boarding a bus – and that’s the beauty of this, its capacity to express everyone’s everyday thoughts and fears at the realisation that such a beast is among them. The disquieting reaction of one couple (glad the hookers are gone from the neighbourhood) also reflects people’s desire to say the unthinkable, despite the horror and tabloid revelations. This unsettling social realist outing is one of a kind with an occasional visual flourish, daring to suggest that a strange looking neighbour might be the real culprit, offering a very unusual twist ending. Definitely not LA LA Land.
