What's On Tonight (Sunday): Darling it's better, down where it's wetter

OceanXplorers

And oh that blowfish blow! Here's what's on television for tonight, Sunday, August 18!

Our Top Pick tonight is the premiere of OceanXplorers (National Geographic & National Geographic Wild,, 9 & 10 p.m.). This series teams James Cameron and the BBC with the passionate researchers at OceanX. They will explore the unexplored and see what we can learn from the creatures that live in the blue part of this blue planet. While the first 2 (of 6) episodes airs tonight — and continues for the next 2 Sundays — the complete season drops Monday on Disney+.

Elsewhere, HBO profiles the Chimp queen, are SEALs heroes or criminals, an Orphan was shot, Lifetime gets Trapped, the Emperor has an outburst, Cops don't like paperwork, and Hollywood might hire Black people.
