Tom Holland and Greg James play 'Sit Down, Stand Up'—a deceptively simple game where they predict whether famous friends are sitting or standing when called, then ring them to find out. Featuring Stormzy, Andrew Garfield, Timothée Chalamet, Greta Thunberg, Lorraine Kelly, Ed Sheeran and more, with hilariously awkward phone calls and Tom's competitive commentary throughout.
