Danny McBride Threatened With 'Monkey Poop' by PETA Over 'Righteous Gemstones'

Danny McBride could be in for a crappy surprise — literally — over the use apparent use of real monkeys in his hit show “The Righteous Gemstones.”

PETA tells TMZ … the org is threatening to send McBride fake monkey poop after spotting what they claim is a real capuchin monkey in the show’s trailer.

PETA claims they have been firing off emails to McBride’s reps and HBO execs demanding primates be left out of the show, and a commitment to never using wild animals in productions again … but haven’t heard back.

Now, the animal rights group says they’ll be watching the upcoming episode on Sunday — and if a live monkey appears, this fake pile of doo-doo is going to show up at the front door of McBride’s production company.

Debbie Metzler, PETA’s Senior Director of Captive Wildlife, tells us … “Danny McBride has all the advanced technology at his fingertips, but he chose to further exploit a suffering monkey who should be in a rainforest, not on a TV set.”
