Documentary maker Louis Theroux feels that Netflix series Tiger King was lacking in terms of an animal rights perspective.
The 49-year-old - one of the first people to interview the documentary series' central figure, Joe Exotic - felt he documentary focused too much on the craziness surrounding Exotic and other big cat zookeepers in the US.
He interviewed Exotic, whose real name is Joseph Maldonado-Passage, back in 2011 for his BBC show America’s Most Dangerous Pets.
Speaking on the Radio 2 Breakfast Show with Zoe Ball on Wednesday, Theroux said that while he did enjoy the show, he thought there should have been more about the poor treatment of the tigers.
"I enjoyed it and I'd known about it because I know one of the people who was involved in making it so I saw it on the horizon," he explained.
"I knew a lot of stuff about the alleged murder for hire plot.

"I thought it was an entertaining and amazing romp through this netherworld of big cat owners and it really gripped my attention."
Theroux was speaking to Ball to plug his Grounded podcast, and added that his only "quibble" with the Tiger King series was its coverage of the animal rights issue.
"I did think the tiger perspective was slightly lost, that was my little quibble," he said.
"I sort of thought here is an animal rights story here which they kind of did at the end a bit but you didn't see the foreground.
"I feel bad even raising that because I thought it was an amazing piece of multi-episode storytelling of the type that I would aspire to do.
"That whole long form immersive documentary storytelling is brlliant."
