Louis Theroux fans will no doubt be fully aware that prior to 2020’s cult documentary  Tiger King  – which took Netflix audiences by storm – it was Theroux himself who had first brought Joe Exotic to our attention within his own work. Back in 2011, Theroux spent some time with the controversial figure, and interviewed him for his series America’s Most Dangerous Pets. Which is why it makes sense that the documentary filmmaker will be returning to the drama-filled world of large cats to do a follow up programme in April.
