Industry is winding down, and it's taking half of a casting directory with it.

HBO and the BBC have confirmed that Ben Platt and Russell Tovey are joining the fifth and final season of the finance drama, currently shooting in the UK. Both are guest roles, but neither is small print. Platt plays Matt Crenshaw, a venture capitalist described as an early backer of a wellness-tech company. That puts him in the same orbit as two other recent additions, Zosia Mamet, playing fitness-influencer-turned-founder Carmen Dame, and Dianna Agron as Skip Binksy, the company's CFO. Read into that what you will. A wellness-tech storyline running through the trading floor and boardroom chaos Industry usually deals in feels like exactly the kind of pivot this show enjoys making.

Tovey, meanwhile, plays Declan P. Davis, deputy to a left-wing politician named Nikesh Shah. Shah is played by Bally Gill, another new face for season five. So Industry is apparently sending its cast into Westminster this time, not just Canary Wharf.

The two join a genuinely stacked list of new arrivals already announced for the closing run. Cary Elwes comes in as an investor. Sam Riley plays an elusive British businessman. Jessica Brown Findlay is a family friend of Sir Henry Muck, the tech founder played by Kit Harington across earlier seasons. Luke Manley and Eduard Poliakov round things out as traders, one of them an execution trader specifically.

For a show that started as a tight ensemble drama about Pierpoint graduates clawing their way up, that's a lot of new money and new faces walking in for the finale.

Season four left Harper (Myha'la) and Yasmin (Marisa Abela) at the top of the ladder they'd spent years climbing, and immediately in trouble because of it. A flashy fintech company arrives in London and drags both women into what Deadline described as a globetrotting cat-and-mouse game. Yasmin's entanglement with Muck complicated things on the personal side. Harper's pull toward an executive named Whitney Halberstram, played by Max Minghella, complicated things further. Neither storyline ended clean.

Industry comes from Mickey Down and Konrad Kay, who created it and continue to write and direct, produced by Bad Wolf for HBO and the BBC. No air date has been set for season five, and with a cast this large still filling out, that's not surprising. What is clear is that the show isn't shrinking on its way out the door. It's adding characters, adding money, and apparently adding a wellness startup nobody asked for.

Whether all of it pays off only becomes clear once the final season actually airs. For now, the call sheet keeps getting longer.
