Will Smith on Slow Horses, working with Gary Oldman and controlling the swear count
Having started his career in stand-up comedy before moving into screenwriting, his television career levelled up when he started working with legendary Scottish satirist Armando Iannucci in the mid-noughties. This collaboration led to a spot in the writers' room on Iannucci's seminal political comedy The Thick of It, where Smith also ended up on screen as Phil, the geeky and pompous special adviser.
