Jak currently enjoys rave reviews in his West End debut, playing Hester in Operation Mincemeat at the Fortune Theatre. He has received critical acclaim for his performance:

★★★★ The Guardian: “the MVP of the five-strong cast remains Jak Malone, who brings effortless distinction to his vastly different roles, from a doughty submarine captain to a camp, creepy coroner. But it’s as Hester Leggett, MI5’s long-serving matron figure, that he steals the show..”

★★★★★ Financial Times: “Among the excellent performers — if I had to commend just one, it would be Malone for his razzamatazz number as the ghoulish pathologist Bernard Spilsbury, his poignant love song as spinster secretary Hester Leggett and his jolly John Barrowman-esque turn as an American airman.”

★★★★ WhatsOnStage: “Jak Malone is a real find, delivering with broad yet precise brush strokes, roles as diverse as an improbably glitzy pathologist, a hearty American pilot, and a genteel, lonely, unexpectedly touching female civil servant.”
