From The White Lotus to Industry, hedonism is everywhere on TV at the moment. Actors, and the ‘wellbeing facilitators’ tasked with keeping them safe, reveal the trick to acting under the influence

“Iam not a big drinker, I don’t do drugs, I don’t smoke,” says Sagar Radia, best known as the ruthless, potty-mouthed trader Rishi Ramdani in the HBO/BBC banking saga Industry. “But when friends and family watch, they’re like: ‘You look like you do know what you’re doing.’”

Nowhere was this more the case than in season three’s White Mischief, an episode focused entirely on the character’s grim descent into gambling addiction, inflamed by booze and cocaine. Previously described by a colleague as “the ghost of Margaret Thatcher in a handsome Asian kid”, here Rishi starts to look more like a disgraced Tory MP in the 90s, as he binges on shots and coke in a seedy casino. At first he’s euphoric – dancing like a drunk uncle at a wedding – but soon his behaviour becomes erratic, his movements shaky and impaired, his legs unsteady. Despite rising debts, he gambles away all he has, and even seems to consider pawning his wedding ring for a few, long seconds. The next morning, we see him stagger into work on a comedown – bloody cuts and bruises all over his face.
