What to Watch Wednesday: Ali Wentworth in Nightcap

Your daily guide to the most interesting stuff happening on TV and streaming. All times Eastern.

PICK OF THE NIGHT

Nightcap

Pop, 8 p.m.

Pop is one of those networks most people don’t really know how to find, but, every now and then, a show gives them a reason to look it up. Nightcap is one of them. Starring Ali Wentworth as the talent booker for a third tier late-night talk show, the offbeat comedy follows the odd, awkward goings-on of the staff behind the scenes staff. Imagine 30 Rock but less caustic and with a revolving door of celebrity guests baked into the plot — Sarah Jessica Parker, Andy Cohen, and Kelly Ripa all make cameos in the premiere.

SERIES DEBUT
