People can't get over incredible comparison between Louis Theroux and his brother

When you think of the name Theroux, your mind probably goes straight to the very famous documentarian, Louis.

However, Louis is not the only Theroux worth mentioning as there is also Marcel. And to avoid any confusion, the pair are brothers.

Yep, there’s plenty of the family who are big names in their respective field, from travel writing dad Paul to cousin Jason, the Mulholland Drive actor.

But fans can’t get over a specific similarity between Louis and his big brother – not to do with their careers.

Premiering on ITV yesterday, Marcel’s latest work is The Playboy Bunny Murder, a two-part documentary looking into the horrific, unsolved murders of three Playboy Bunnies.

Louis took to X to encourage people to watch the new documentary, writing: “I wouldn’t normally promote a film that’s on at exactly the same time as mine on a rival channel but it’s different when it’s been made by my brother @therouvian.

“I haven’t seen it yet and look forward to watching AFTER I rewatch mine at 9pm tomorrow.”
